499 MatGetRow - Gets a row of a matrix. You MUST call MatRestoreRow()
500 for each row that you get to ensure that your application does
501 not bleed memory.
502
503 Not Collective
504
505 Input Parameters:
506+ mat - the matrix
507- row - the row to get
508
509 Output Parameters:
510+ ncols - if not NULL, the number of nonzeros in the row
511. cols - if not NULL, the column numbers
512- vals - if not NULL, the values
513
514 Notes:
515 This routine is provided for people who need to have direct access
516 to the structure of a matrix. We hope that we provide enough
517 high-level matrix routines that few users will need it.
518
519 MatGetRow() always returns 0-based column indices, regardless of
520 whether the internal representation is 0-based (default) or 1-based.
521
522 For better efficiency, set cols and/or vals to NULL if you do
523 not wish to extract these quantities.
524
525 The user can only examine the values extracted with MatGetRow();
526 the values cannot be altered. To change the matrix entries, one
527 must use MatSetValues().
528
529 You can only have one call to MatGetRow() outstanding for a particular
530 matrix at a time, per processor. MatGetRow() can only obtain rows
531 associated with the given processor, it cannot get rows from the
532 other processors; for that we suggest using MatCreateSubMatrices(), then
533 MatGetRow() on the submatrix. The row index passed to MatGetRow()
534 is in the global number of rows.
535
536 Fortran Notes:
537 The calling sequence from Fortran is
538.vb
539 MatGetRow(matrix,row,ncols,cols,values,ierr)
540 Mat matrix (input)
541 integer row (input)
542 integer ncols (output)
543 integer cols(maxcols) (output)
544 double precision (or double complex) values(maxcols) output
545.ve
546 where maxcols >= maximum nonzeros in any row of the matrix.
547
548
549 Caution:
550 Do not try to change the contents of the output arrays (cols and vals).
551 In some cases, this may corrupt the matrix.

610 MatRestoreRow - Frees any temporary space allocated by MatGetRow().
611
612 Not Collective
613
614 Input Parameters:
615+ mat - the matrix
616. row - the row to get
617. ncols, cols - the number of nonzeros and their columns
618- vals - if nonzero the column values
619
620 Notes:
621 This routine should be called after you have finished examining the entries.
622
623 This routine zeros out ncols, cols, and vals. This is to prevent accidental
624 us of the array after it has been restored. If you pass NULL, it will
625 not zero the pointers. Use of cols or vals after MatRestoreRow is invalid.
626
627 Fortran Notes:
628 The calling sequence from Fortran is
629.vb
630 MatRestoreRow(matrix,row,ncols,cols,values,ierr)
631 Mat matrix (input)
632 integer row (input)
633 integer ncols (output)
634 integer cols(maxcols) (output)
635 double precision (or double complex) values(maxcols) output
636.ve
637 Where maxcols >= maximum nonzeros in any row of the matrix.
638
639 In Fortran MatRestoreRow() MUST be called after MatGetRow()
640 before another call to MatGetRow() can be made.

890 Input Parameters:
891+ mat - the matrix
892- viewer - visualization context
893
894 Notes:
895 The available visualization contexts include
896+ PETSC_VIEWER_STDOUT_SELF - for sequential matrices
897. PETSC_VIEWER_STDOUT_WORLD - for parallel matrices created on PETSC_COMM_WORLD
898. PETSC_VIEWER_STDOUT_(comm) - for matrices created on MPI communicator comm
899- PETSC_VIEWER_DRAW_WORLD - graphical display of nonzero structure
900
901 The user can open alternative visualization contexts with
902+ PetscViewerASCIIOpen() - Outputs matrix to a specified file
903. PetscViewerBinaryOpen() - Outputs matrix in binary to a
904 specified file; corresponding input uses MatLoad()
905. PetscViewerDrawOpen() - Outputs nonzero matrix structure to
906 an X window display
907- PetscViewerSocketOpen() - Outputs matrix to Socket viewer.
908 Currently only the sequential dense and AIJ
909 matrix types support the Socket viewer.
910
911 The user can call PetscViewerPushFormat() to specify the output
912 format of ASCII printed objects (when using PETSC_VIEWER_STDOUT_SELF,
913 PETSC_VIEWER_STDOUT_WORLD and PetscViewerASCIIOpen). Available formats include
914+ PETSC_VIEWER_DEFAULT - default, prints matrix contents
915. PETSC_VIEWER_ASCII_MATLAB - prints matrix contents in Matlab format
916. PETSC_VIEWER_ASCII_DENSE - prints entire matrix including zeros
917. PETSC_VIEWER_ASCII_COMMON - prints matrix contents, using a sparse
918 format common among all matrix types
919. PETSC_VIEWER_ASCII_IMPL - prints matrix contents, using an implementation-specific
920 format (which is in many cases the same as the default)
921. PETSC_VIEWER_ASCII_INFO - prints basic information about the matrix
922 size and structure (not the matrix entries)
923- PETSC_VIEWER_ASCII_INFO_DETAIL - prints more detailed information about
924 the matrix structure
925
926 Options Database Keys:
927+ -mat_view ::ascii_info - Prints info on matrix at conclusion of MatAssemblyEnd()
928. -mat_view ::ascii_info_detail - Prints more detailed info
929. -mat_view - Prints matrix in ASCII format
930. -mat_view ::ascii_matlab - Prints matrix in Matlab format
931. -mat_view draw - PetscDraws nonzero structure of matrix, using MatView() and PetscDrawOpenX().
932. -display <name> - Sets display name (default is host)
933. -draw_pause <sec> - Sets number of seconds to pause after display
934. -mat_view socket - Sends matrix to socket, can be accessed from Matlab (see Users-Manual: ch_matlab for details)
935. -viewer_socket_machine <machine> -
936. -viewer_socket_port <port> -
937. -mat_view binary - save matrix to file in binary format
938- -viewer_binary_filename <name> -
939 Level: beginner
940
941 Notes:
942 The ASCII viewers are only recommended for small matrices on at most a moderate number of processes,
943 the program will seemingly hang and take hours for larger matrices, for larger matrices one should use the binary format.
944
945 See the manual page for MatLoad() for the exact format of the binary file when the binary
946 viewer is used.
947
948 See share/petsc/matlab/PetscBinaryRead.m for a Matlab code that can read in the binary file when the binary
949 viewer is used.
950
951 One can use '-mat_view draw -draw_pause -1' to pause the graphical display of matrix nonzero structure,
952 and then use the following mouse functions.
953+ left mouse: zoom in
954. middle mouse: zoom out
955- right mouse: continue with the simulation

1081/*@C
1082 MatLoad - Loads a matrix that has been stored in binary/HDF5 format
1083 with MatView(). The matrix format is determined from the options database.
1084 Generates a parallel MPI matrix if the communicator has more than one
1085 processor. The default matrix type is AIJ.
1086
1087 Collective on PetscViewer
1088
1089 Input Parameters:
1090+ newmat - the newly loaded matrix, this needs to have been created with MatCreate()
1091 or some related function before a call to MatLoad()
1092- viewer - binary/HDF5 file viewer
1093
1094 Options Database Keys:
1095 Used with block matrix formats (MATSEQBAIJ, ...) to specify
1096 block size
1097. -matload_block_size <bs>
1098
1099 Level: beginner
1100
1101 Notes:
1102 If the Mat type has not yet been given then MATAIJ is used, call MatSetFromOptions() on the
1103 Mat before calling this routine if you wish to set it from the options database.
1104
1105 MatLoad() automatically loads into the options database any options
1106 given in the file filename.info where filename is the name of the file
1107 that was passed to the PetscViewerBinaryOpen(). The options in the info
1108 file will be ignored if you use the -viewer_binary_skip_info option.
1109
1110 If the type or size of newmat is not set before a call to MatLoad, PETSc
1111 sets the default matrix type AIJ and sets the local and global sizes.
1112 If type and/or size is already set, then the same are used.
1113
1114 In parallel, each processor can load a subset of rows (or the
1115 entire matrix). This routine is especially useful when a large
1116 matrix is stored on disk and only part of it is desired on each
1117 processor. For example, a parallel solver may access only some of
1118 the rows from each processor. The algorithm used here reads
1119 relatively small blocks of data rather than reading the entire
1120 matrix and then subsetting it.
1121
1122 Viewer's PetscViewerType must be either PETSCVIEWERBINARY or PETSCVIEWERHDF5.
1123 Such viewer can be created using PetscViewerBinaryOpen()/PetscViewerHDF5Open(),
1124 or the sequence like
1125$ PetscViewer v;
1126$ PetscViewerCreate(PETSC_COMM_WORLD,&v);
1127$ PetscViewerSetType(v,PETSCVIEWERBINARY);
1128$ PetscViewerSetFromOptions(v);
1129$ PetscViewerFileSetMode(v,FILE_MODE_READ);
1130$ PetscViewerFileSetName(v,"datafile");
1131 The optional PetscViewerSetFromOptions() call allows to override PetscViewerSetType() using option
1132$ -viewer_type {binary,hdf5}
1133
1134 See the example src/ksp/ksp/examples/tutorials/ex27.c with the first approach,
1135 and src/mat/examples/tutorials/ex10.c with the second approach.
1136
1137 Notes about the PETSc binary format:
1138 In case of PETSCVIEWERBINARY, a native PETSc binary format is used. Each of the blocks
1139 is read onto rank 0 and then shipped to its destination rank, one after another.
1140 Multiple objects, both matrices and vectors, can be stored within the same file.
1141 Their PetscObject name is ignored; they are loaded in the order of their storage.
1142
1143 Most users should not need to know the details of the binary storage
1144 format, since MatLoad() and MatView() completely hide these details.
1145 But for anyone who's interested, the standard binary matrix storage
1146 format is
1147
1148$ int MAT_FILE_CLASSID
1149$ int number of rows
1150$ int number of columns
1151$ int total number of nonzeros
1152$ int *number nonzeros in each row
1153$ int *column indices of all nonzeros (starting index is zero)
1154$ PetscScalar *values of all nonzeros
1155
1156 PETSc automatically does the byte swapping for
1157machines that store the bytes reversed, e.g. DEC alpha, freebsd,
1158linux, Windows and the paragon; thus if you write your own binary
1159read/write routines you have to swap the bytes; see PetscBinaryRead()
1160and PetscBinaryWrite() to see how this may be done.
1161
1162 Notes about the HDF5 (MATLAB MAT-File Version 7.3) format:
1163 In case of PETSCVIEWERHDF5, a parallel HDF5 reader is used.
1164 Each processor's chunk is loaded independently by its owning rank.
1165 Multiple objects, both matrices and vectors, can be stored within the same file.
1166 They are looked up by their PetscObject name.
1167
1168 As the MATLAB MAT-File Version 7.3 format is also a HDF5 flavor, we decided to use
1169 by default the same structure and naming of the AIJ arrays and column count
1170 within the HDF5 file. This means that a MAT file saved with -v7.3 flag, e.g.
1171$ save example.mat A b -v7.3
1172 can be directly read by this routine (see Reference 1 for details).
1173 Note that depending on your MATLAB version, this format might be a default,
1174 otherwise you can set it as default in Preferences.
1175
1176 Unless -nocompression flag is used to save the file in MATLAB,
1177 PETSc must be configured with ZLIB package.
1178
1179 See also examples src/mat/examples/tutorials/ex10.c and src/ksp/ksp/examples/tutorials/ex27.c
1180
1181 Current HDF5 (MAT-File) limitations:
1182 This reader currently supports only real MATSEQAIJ, MATMPIAIJ, MATSEQDENSE and MATMPIDENSE matrices.
1183
1184 Corresponding MatView() is not yet implemented.
1185
1186 The loaded matrix is actually a transpose of the original one in MATLAB,
1187 unless you push PETSC_VIEWER_HDF5_MAT format (see examples above).
1188 With this format, matrix is automatically transposed by PETSc,
1189 unless the matrix is marked as SPD or symmetric
1190 (see MatSetOption(), MAT_SPD, MAT_SYMMETRIC).

1301/*@C
1302 MatSetValues - Inserts or adds a block of values into a matrix.
1303 These values may be cached, so MatAssemblyBegin() and MatAssemblyEnd()
1304 MUST be called after all calls to MatSetValues() have been completed.
1305
1306 Not Collective
1307
1308 Input Parameters:
1309+ mat - the matrix
1310. v - a logically two-dimensional array of values
1311. m, idxm - the number of rows and their global indices
1312. n, idxn - the number of columns and their global indices
1313- addv - either ADD_VALUES or INSERT_VALUES, where
1314 ADD_VALUES adds values to any existing entries, and
1315 INSERT_VALUES replaces existing entries with new values
1316
1317 Notes:
1318 If you create the matrix yourself (that is not with a call to DMCreateMatrix()) then you MUST call MatXXXXSetPreallocation() or
1319 MatSetUp() before using this routine
1320
1321 By default the values, v, are row-oriented. See MatSetOption() for other options.
1322
1323 Calls to MatSetValues() with the INSERT_VALUES and ADD_VALUES
1324 options cannot be mixed without intervening calls to the assembly
1325 routines.
1326
1327 MatSetValues() uses 0-based row and column numbers in Fortran
1328 as well as in C.
1329
1330 Negative indices may be passed in idxm and idxn, these rows and columns are
1331 simply ignored. This allows easily inserting element stiffness matrices
1332 with homogeneous Dirchlet boundary conditions that you don't want represented
1333 in the matrix.
1334
1335 Efficiency Alert:
1336 The routine MatSetValuesBlocked() may offer much better efficiency
1337 for users of block sparse formats (MATSEQBAIJ and MATMPIBAIJ).
1338
1339 Level: beginner
1340
1341 Developer Notes:
1342 This is labeled with C so does not automatically generate Fortran stubs and interfaces
1343 because it requires multiple Fortran interfaces depending on which arguments are scalar or arrays.

1500 MatSetValuesStencil - Inserts or adds a block of values into a matrix.
1501 Using structured grid indexing
1502
1503 Not Collective
1504
1505 Input Parameters:
1506+ mat - the matrix
1507. m - number of rows being entered
1508. idxm - grid coordinates (and component number when dof > 1) for matrix rows being entered
1509. n - number of columns being entered
1510. idxn - grid coordinates (and component number when dof > 1) for matrix columns being entered
1511. v - a logically two-dimensional array of values
1512- addv - either ADD_VALUES or INSERT_VALUES, where
1513 ADD_VALUES adds values to any existing entries, and
1514 INSERT_VALUES replaces existing entries with new values
1515
1516 Notes:
1517 By default the values, v, are row-oriented. See MatSetOption() for other options.
1518
1519 Calls to MatSetValuesStencil() with the INSERT_VALUES and ADD_VALUES
1520 options cannot be mixed without intervening calls to the assembly
1521 routines.
1522
1523 The grid coordinates are across the entire grid, not just the local portion
1524
1525 MatSetValuesStencil() uses 0-based row and column numbers in Fortran
1526 as well as in C.
1527
1528 For setting/accessing vector values via array coordinates you can use the DMDAVecGetArray() routine
1529
1530 In order to use this routine you must either obtain the matrix with DMCreateMatrix()
1531 or call MatSetLocalToGlobalMapping() and MatSetStencil() first.
1532
1533 The columns and rows in the stencil passed in MUST be contained within the
1534 ghost region of the given process as set with DMDACreateXXX() or MatSetStencil(). For example,
1535 if you create a DMDA with an overlap of one grid level and on a particular process its first
1536 local nonghost x logical coordinate is 6 (so its first ghost x logical coordinate is 5) the
1537 first i index you can use in your column and row indices in MatSetStencil() is 5.
1538
1539 In Fortran idxm and idxn should be declared as
1540$ MatStencil idxm(4,m),idxn(4,n)
1541 and the values inserted using
1542$ idxm(MatStencil_i,1) = i
1543$ idxm(MatStencil_j,1) = j
1544$ idxm(MatStencil_k,1) = k
1545$ idxm(MatStencil_c,1) = c
1546 etc
1547
1548 For periodic boundary conditions use negative indices for values to the left (below 0; that are to be
1549 obtained by wrapping values from right edge). For values to the right of the last entry using that index plus one
1550 etc to obtain values that obtained by wrapping the values from the left edge. This does not work for anything but the
1551 DM_BOUNDARY_PERIODIC boundary type.
1552
1553 For indices that don't mean anything for your case (like the k index when working in 2d) or the c index when you have
1554 a single value per point) you can skip filling those indices.
1555
1556 Inspired by the structured grid interface to the HYPRE package
1557 (https://computation.llnl.gov/projects/hypre-scalable-linear-solvers-multigrid-methods)
1558
1559 Efficiency Alert:
1560 The routine MatSetValuesBlockedStencil() may offer much better efficiency
1561 for users of block sparse formats (MATSEQBAIJ and MATMPIBAIJ).

1620+ mat - the matrix
1621. m - number of rows being entered
1622. idxm - grid coordinates for matrix rows being entered
1623. n - number of columns being entered

1651 local nonghost x logical coordinate is 6 (so its first ghost x logical coordinate is 5) the
1652 first i index you can use in your column and row indices in MatSetStencil() is 5.
1653
1654 In Fortran idxm and idxn should be declared as
1655$ MatStencil idxm(4,m),idxn(4,n)
1656 and the values inserted using
1657$ idxm(MatStencil_i,1) = i
1658$ idxm(MatStencil_j,1) = j
1659$ idxm(MatStencil_k,1) = k
1660 etc
1661
1662 Negative indices may be passed in idxm and idxn, these rows and columns are
1663 simply ignored. This allows easily inserting element stiffness matrices
1664 with homogeneous Dirchlet boundary conditions that you don't want represented
1665 in the matrix.

1773 MatSetValuesBlocked - Inserts or adds a block of values into a matrix.
1774
1775 Not Collective
1776
1777 Input Parameters:
1778+ mat - the matrix
1779. v - a logically two-dimensional array of values
1780. m, idxm - the number of block rows and their global block indices
1781. n, idxn - the number of block columns and their global block indices
1782- addv - either ADD_VALUES or INSERT_VALUES, where
1783 ADD_VALUES adds values to any existing entries, and
1784 INSERT_VALUES replaces existing entries with new values
1785
1786 Notes:
1787 If you create the matrix yourself (that is not with a call to DMCreateMatrix()) then you MUST call
1788 MatXXXXSetPreallocation() or MatSetUp() before using this routine.
1789
1790 The m and n count the NUMBER of blocks in the row direction and column direction,
1791 NOT the total number of rows/columns; for example, if the block size is 2 and
1792 you are passing in values for rows 2,3,4,5 then m would be 2 (not 4).
1793 The values in idxm would be 1 2; that is the first index for each block divided by
1794 the block size.
1795
1796 Note that you must call MatSetBlockSize() when constructing this matrix (before
1797 preallocating it).
1798
1799 By default the values, v, are row-oriented, so the layout of
1800 v is the same as for MatSetValues(). See MatSetOption() for other options.
1801
1802 Calls to MatSetValuesBlocked() with the INSERT_VALUES and ADD_VALUES
1803 options cannot be mixed without intervening calls to the assembly
1804 routines.
1805
1806 MatSetValuesBlocked() uses 0-based row and column numbers in Fortran
1807 as well as in C.
1808
1809 Negative indices may be passed in idxm and idxn, these rows and columns are
1810 simply ignored. This allows easily inserting element stiffness matrices
1811 with homogeneous Dirchlet boundary conditions that you don't want represented
1812 in the matrix.
1813
1814 Each time an entry is set within a sparse matrix via MatSetValues(),
1815 internal searching must be done to determine where to place the
1816 data in the matrix storage space. By instead inserting blocks of
1817 entries via MatSetValuesBlocked(), the overhead of matrix assembly is
1818 reduced.
1819
1820 Example:
1821$ Suppose m=n=2 and block size(bs) = 2 The array is
1822$
1823$ 1 2 | 3 4
1824$ 5 6 | 7 8
1825$ - - - | - - -
1826$ 9 10 | 11 12
1827$ 13 14 | 15 16
1828$
1829$ v[] should be passed in like
1830$ v[] = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]
1831$
1832$ If you are not using row oriented storage of v (that is you called MatSetOption(mat,MAT_ROW_ORIENTED,PETSC_FALSE)) then
1833$ v[] = [1,5,9,13,2,6,10,14,3,7,11,15,4,8,12,16]

1900 MatGetValues - Gets a block of values from a matrix.
1901
1902 Not Collective; currently only returns a local block
1903
1904 Input Parameters:
1905+ mat - the matrix
1906. v - a logically two-dimensional array for storing the values
1907. m, idxm - the number of rows and their global indices
1908- n, idxn - the number of columns and their global indices
1909
1910 Notes:
1911 The user must allocate space (m*n PetscScalars) for the values, v.
1912 The values, v, are then returned in a row-oriented format,
1913 analogous to that used by default in MatSetValues().
1914
1915 MatGetValues() uses 0-based row and column numbers in
1916 Fortran as well as in C.
1917
1918 MatGetValues() requires that the matrix has been assembled
1919 with MatAssemblyBegin()/MatAssemblyEnd(). Thus, calls to
1920 MatSetValues() and MatGetValues() CANNOT be made in succession
1921 without intermediate matrix assembly.
1922
1923 Negative row or column indices will be ignored and those locations in v[] will be
1924 left unchanged.

1953 MatSetValuesBatch - Adds (ADD_VALUES) many blocks of values into a matrix at once. The blocks must all be square and
1954 the same size. Currently, this can only be called once and creates the given matrix.
1955
1956 Not Collective
1957
1958 Input Parameters:
1959+ mat - the matrix
1960. nb - the number of blocks
1961. bs - the number of rows (and columns) in each block
1962. rows - a concatenation of the rows for each block
1963- v - a concatenation of logically two-dimensional arrays of values
1964
1965 Notes:
1966 In the future, we will extend this routine to handle rectangular blocks, and to allow multiple calls for a given matrix.

2098
2099 Input Parameters:
2100+ mat - the matrix
2101. nrow, irow - number of rows and their local indices
2102. ncol, icol - number of columns and their local indices

2104- addv - either INSERT_VALUES or ADD_VALUES, where
2105 ADD_VALUES adds values to any existing entries, and
2106 INSERT_VALUES replaces existing entries with new values
2107
2108 Notes:
2109 If you create the matrix yourself (that is not with a call to DMCreateMatrix()) then you MUST call MatXXXXSetPreallocation() or
2110 MatSetUp() before using this routine

2112 If you create the matrix yourself (that is not with a call to DMCreateMatrix()) then you MUST call MatSetLocalToGlobalMapping() before using this routine

2114 Calls to MatSetValuesLocal() with the INSERT_VALUES and ADD_VALUES
2115 options cannot be mixed without intervening calls to the assembly

2180 MatSetValuesBlockedLocal - Inserts or adds values into certain locations of a matrix,
2181 using a local ordering of the nodes a block at a time.
2182
2183 Not Collective
2184
2185 Input Parameters:
2186+ x - the matrix
2187. nrow, irow - number of rows and their local indices
2188. ncol, icol - number of columns and their local indices
2189. y - a logically two-dimensional array of values
2190- addv - either INSERT_VALUES or ADD_VALUES, where
2191 ADD_VALUES adds values to any existing entries, and
2192 INSERT_VALUES replaces existing entries with new values
2193
2194 Notes:
2195 If you create the matrix yourself (that is not with a call to DMCreateMatrix()) then you MUST call MatXXXXSetPreallocation() or
2196 MatSetUp() before using this routine
2197
2198 If you create the matrix yourself (that is not with a call to DMCreateMatrix()) then you MUST call MatSetBlockSize() and MatSetLocalToGlobalMapping()
2199 before using this routineBefore calling MatSetValuesLocal(), the user must first set the
2200
2201 Calls to MatSetValuesBlockedLocal() with the INSERT_VALUES and ADD_VALUES
2202 options cannot be mixed without intervening calls to the assembly
2203 routines.
2204
2205 These values may be cached, so MatAssemblyBegin() and MatAssemblyEnd()
2206 MUST be called after all calls to MatSetValuesBlockedLocal() have been completed.
2207
2208 Level: intermediate
2209
2210 Developer Notes:
2211 This is labeled with C so does not automatically generate Fortran stubs and interfaces
2212 because it requires multiple Fortran interfaces depending on which arguments are scalar or arrays.

2794
2795 Collective on Mat if MAT_GLOBAL_MAX or MAT_GLOBAL_SUM is used as the flag
2796
2797 Input Parameters:
2798. mat - the matrix
2799
2800 Output Parameters:
2801+ flag - flag indicating the type of parameters to be returned
2802 (MAT_LOCAL - local matrix, MAT_GLOBAL_MAX - maximum over all processors,
2803 MAT_GLOBAL_SUM - sum over all processors)
2804- info - matrix information context
2805
2806 Notes:
2807 The MatInfo context contains a variety of matrix data, including
2808 number of nonzeros allocated and used, number of mallocs during
2809 matrix assembly, etc. Additional information for factored matrices
2810 is provided (such as the fill ratio, number of mallocs during
2811 factorization, etc.). Much of this info is printed to PETSC_STDOUT
2812 when using the runtime options
2813$ -info -mat_view ::ascii_info
2814
2815 Example for C/C++ Users:
2816 See the file ${PETSC_DIR}/include/petscmat.h for a complete list of
2817 data within the MatInfo context. For example,
2818.vb
2819 MatInfo info;

2823 MatGetInfo(A,MAT_LOCAL,&info);
2824 mal = info.mallocs;
2825 nz_a = info.nz_allocated;
2826.ve
2827
2828 Example for Fortran Users:
2829 Fortran users should declare info as a double precision
2830 array of dimension MAT_INFO_SIZE, and then extract the parameters
2831 of interest. See the file ${PETSC_DIR}/include/petsc/finclude/petscmat.h
2832 a complete list of parameter names.

2884 Collective on Mat
2885
2886 Input Parameters:
2887+ mat - the matrix
2888. row - row permutation
2889. col - column permutation
2890- info - options for factorization, includes
2891$ fill - expected fill as ratio of original fill.
2892$ dtcol - pivot tolerance (0 no pivot, 1 full column pivoting)
2893$ Run with the option -info to determine an optimal value to use
2894
2895 Notes:
2896 Most users should employ the simplified KSP interface for linear solvers
2897 instead of working directly with matrix algebra routines such as this.
2898 See, e.g., KSPCreate().
2899
2900 This changes the state of the matrix to a factored matrix; it cannot be used
2901 for example with MatSetValues() unless one first calls MatSetUnfactored().

2943
2944 Input Parameters:
2945+ mat - the matrix
2946. row - row permutation
2947. col - column permutation
2948- info - structure containing
2949$ levels - number of levels of fill.
2950$ expected fill - as ratio of original fill.
2951$ 1 or 0 - indicating force fill on diagonal (improves robustness for matrices
2952 missing diagonal entries)
2953
2954 Notes:
2955 Probably really in-place only when level of fill is zero, otherwise allocates
2956 new space to store factored matrix and deletes previous memory.

2997 Collective on Mat
2998
2999 Input Parameters:
3000+ fact - the factor matrix obtained with MatGetFactor()
3001. mat - the matrix
3002. row, col - row and column permutations
3003- info - options for factorization, includes

3260 MatSolve - Solves A x = b, given a factored matrix.
3261
3262 Neighbor-wise Collective on Mat
3263
3264 Input Parameters:
3265+ mat - the factored matrix
3266- b - the right-hand-side vector
3267
3268 Output Parameter:
3269. x - the result vector
3270
3271 Notes:
3272 The vectors b and x cannot be the same. I.e., one cannot
3273 call MatSolve(A,x,x).
3274
3275 Notes:
3276 Most users should employ the simplified KSP interface for linear solvers
3277 instead of working directly with matrix algebra routines such as this.
3278 See, e.g., KSPCreate().

3354 MatMatSolve - Solves A X = B, given a factored matrix.
3355
3356 Neighbor-wise Collective on Mat
3357
3358 Input Parameters:
3359+ A - the factored matrix
3360- B - the right-hand-side matrix (dense matrix)
3361
3362 Output Parameter:
3363. X - the result matrix (dense matrix)
3364
3365 Notes:
3366 The matrices b and x cannot be the same. I.e., one cannot
3367 call MatMatSolve(A,x,x).
3368
3369 Notes:
3370 Most users should usually employ the simplified KSP interface for linear solvers
3371 instead of working directly with matrix algebra routines such as this.
3372 See, e.g., KSPCreate(). However KSP can only solve for one vector (column of X)
3373 at a time.
3374
3375 When using SuperLU_Dist as a parallel solver PETSc will use the SuperLU_Dist functionality to solve multiple right hand sides simultaneously. For MUMPS
3376 it calls a separate solve for each right hand side since MUMPS does not yet support distributed right hand sides.
3377
3378 Since the resulting matrix X must always be dense we do not support sparse representation of the matrix B.

3481+ A - the factored matrix

3483
3484 Output Parameter:
3485. X - the result matrix (dense matrix)

3487 Notes:
3488 Most users should usually employ the simplified KSP interface for linear solvers
3489 instead of working directly with matrix algebra routines such as this.
3490 See, e.g., KSPCreate(). However KSP can only solve for one vector (column of X)
3491 at a time.
3492
3493 For MUMPS, it only supports centralized sparse compressed column format on the host processor for right hand side matrix. User must create B^T in sparse compressed row format on the host processor and call MatMatTransposeSolve() to implement MUMPS' MatMatSolve().

3533 Input Parameters:
3534+ mat - the factored matrix
3535- b - the right-hand-side vector
3536
3537 Output Parameter:
3538. x - the result vector
3539
3540 Notes:
3541 MatSolve() should be used for most applications, as it performs
3542 a forward solve followed by a backward solve.
3543
3544 The vectors b and x cannot be the same, i.e., one cannot
3545 call MatForwardSolve(A,x,x).
3546
3547 For matrix in seqsbaij format with block size larger than 1,
3548 the diagonal blocks are not implemented as D = D^(1/2) * D^(1/2) yet.
3549 MatForwardSolve() solves U^T*D y = b, and
3550 MatBackwardSolve() solves U x = y.
3551 Thus they do not provide a symmetric preconditioner.
3552
3553 Most users should employ the simplified KSP interface for linear solvers
3554 instead of working directly with matrix algebra routines such as this.

3589 MatBackwardSolve - Solves U x = b, given a factored matrix, A = LU.
3590 D^(1/2) U x = b, given a factored symmetric matrix, A = U^T*D*U,
3591
3592 Neighbor-wise Collective on Mat
3593
3594 Input Parameters:
3595+ mat - the factored matrix
3596- b - the right-hand-side vector
3597
3598 Output Parameter:
3599. x - the result vector
3600
3601 Notes:
3602 MatSolve() should be used for most applications, as it performs
3603 a forward solve followed by a backward solve.
3604
3605 The vectors b and x cannot be the same. I.e., one cannot
3606 call MatBackwardSolve(A,x,x).
3607
3608 For matrix in seqsbaij format with block size larger than 1,
3609 the diagonal blocks are not implemented as D = D^(1/2) * D^(1/2) yet.
3610 MatForwardSolve() solves U^T*D y = b, and
3611 MatBackwardSolve() solves U x = y.
3612 Thus they do not provide a symmetric preconditioner.
3613
3614 Most users should employ the simplified KSP interface for linear solvers
3615 instead of working directly with matrix algebra routines such as this.
3616 See, e.g., KSPCreate().

3776 MatSolveTransposeAdd - Computes x = y + inv(Transpose(A)) b, given a
3777 factored matrix.
3778
3779 Neighbor-wise Collective on Mat
3780
3781 Input Parameters:
3782+ mat - the factored matrix
3783. b - the right-hand-side vector
3784- y - the vector to be added to
3785
3786 Output Parameter:
3787. x - the result vector
3788
3789 Notes:
3790 The vectors b and x cannot be the same. I.e., one cannot
3791 call MatSolveTransposeAdd(A,x,y,x).
3792
3793 Most users should employ the simplified KSP interface for linear solvers
3794 instead of working directly with matrix algebra routines such as this.
3795 See, e.g., KSPCreate().

3853/*@
3854 MatSOR - Computes relaxation (SOR, Gauss-Seidel) sweeps.
3855
3856 Neighbor-wise Collective on Mat
3857
3858 Input Parameters:
3859+ mat - the matrix
3860. b - the right hand side
3861. omega - the relaxation factor
3862. flag - flag indicating the type of SOR (see below)
3863. shift - diagonal shift
3864. its - the number of iterations
3865- lits - the number of local iterations
3866
3867 Output Parameters:
3868. x - the solution (can contain an initial guess, use option SOR_ZERO_INITIAL_GUESS to indicate no guess)
3869
3870 SOR Flags:
3871+ SOR_FORWARD_SWEEP - forward SOR
3872. SOR_BACKWARD_SWEEP - backward SOR
3873. SOR_SYMMETRIC_SWEEP - SSOR (symmetric SOR)
3874. SOR_LOCAL_FORWARD_SWEEP - local forward SOR
3875. SOR_LOCAL_BACKWARD_SWEEP - local forward SOR
3876. SOR_LOCAL_SYMMETRIC_SWEEP - local SSOR
3877. SOR_APPLY_UPPER, SOR_APPLY_LOWER - applies
3878 upper/lower triangular part of matrix to
3879 vector (with omega)
3880- SOR_ZERO_INITIAL_GUESS - zero initial guess
3881
3882 Notes:
3883 SOR_LOCAL_FORWARD_SWEEP, SOR_LOCAL_BACKWARD_SWEEP, and
3884 SOR_LOCAL_SYMMETRIC_SWEEP perform separate independent smoothings
3885 on each processor.
3886
3887 Application programmers will not generally use MatSOR() directly,
3888 but instead will employ the KSP/PC interface.
3889
3890 Notes:
3891 for BAIJ, SBAIJ, and AIJ matrices with Inodes this does a block SOR smoothing, otherwise it does a pointwise smoothing
3892
3893 Notes for Advanced Users:
3894 The flags are implemented as bitwise inclusive or operations.
3895 For example, use (SOR_ZERO_INITIAL_GUESS | SOR_SYMMETRIC_SWEEP)
3896 to specify a zero initial guess for SSOR.
3897
3898 Most users should employ the simplified KSP interface for linear solvers
3899 instead of working directly with matrix algebra routines such as this.
3900 See, e.g., KSPCreate().
3901
3902 Vectors x and b CANNOT be the same
3903
3904 Developer Note: We should add block SOR support for AIJ matrices with block size set to great than one and no inodes

3968 MatCopy - Copies a matrix to another matrix.
3969
3970 Collective on Mat
3971
3972 Input Parameters:
3973+ A - the matrix
3974- str - SAME_NONZERO_PATTERN or DIFFERENT_NONZERO_PATTERN
3975
3976 Output Parameter:
3977. B - where the copy is put
3978
3979 Notes:
3980 If you use SAME_NONZERO_PATTERN then the two matrices had better have the
3981 same nonzero pattern or the routine will crash.
3982
3983 MatCopy() copies the matrix entries of a matrix to another existing
3984 matrix (after first zeroing the second matrix). A related routine is
3985 MatConvert(), which first creates a new matrix and then copies the data.

4029/*@C
4030 MatConvert - Converts a matrix to another matrix, either of the same
4031 or different type.
4032
4033 Collective on Mat
4034
4035 Input Parameters:
4036+ mat - the matrix
4037. newtype - new matrix type. Use MATSAME to create a new matrix of the
4038 same type as the original matrix.
4039- reuse - denotes if the destination matrix is to be created or reused.
4040 Use MAT_INPLACE_MATRIX for inplace conversion (that is when you want the input mat to be changed to contain the matrix in the new format), otherwise use
4041 MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX (can only be used after the first call was made with MAT_INITIAL_MATRIX, causes the matrix space in M to be reused).
4042
4043 Output Parameter:
4044. M - pointer to place new matrix
4045
4046 Notes:
4047 MatConvert() first creates a new matrix and then copies the data from
4048 the first matrix. A related routine is MatCopy(), which copies the matrix
4049 entries of one matrix to another already existing matrix context.
4050
4051 Cannot be used to convert a sequential matrix to parallel or parallel to sequential,
4052 the MPI communicator of the generated matrix is always the same as the communicator
4053 of the input matrix.

4500 MatDuplicate - Duplicates a matrix including the non-zero structure.
4501
4502 Collective on Mat
4503
4504 Input Parameters:
4505+ mat - the matrix
4506- op - One of MAT_DO_NOT_COPY_VALUES, MAT_COPY_VALUES, or MAT_SHARE_NONZERO_PATTERN.
4507 See the manual page for MatDuplicateOption for an explanation of these options.
4508

4513
4514 Notes:
4515 You cannot change the nonzero pattern for the parent or child matrix if you use MAT_SHARE_NONZERO_PATTERN.
4516 When original mat is a product of matrix operation, e.g., an output of MatMatMult() or MatCreateSubMatrix(), only the simple matrix data structure of mat is duplicated and the internal data structures created for the reuse of previous matrix operations are not duplicated. User should not use MatDuplicate() to create new matrix M if M is intended to be reused as the product of matrix operation.

4802 MatTranspose - Computes an in-place or out-of-place transpose of a matrix.
4803
4804 Collective on Mat
4805
4806 Input Parameter:
4807+ mat - the matrix to transpose
4808- reuse - either MAT_INITIAL_MATRIX, MAT_REUSE_MATRIX, or MAT_INPLACE_MATRIX
4809
4810 Output Parameters:
4811. B - the transpose
4812
4813 Notes:
4814 If you use MAT_INPLACE_MATRIX then you must pass in &mat for B
4815
4816 MAT_REUSE_MATRIX causes the B matrix from a previous call to this function with MAT_INITIAL_MATRIX to be used
4817
4818 Consider using MatCreateTranspose() instead if you only need a matrix that behaves like the transpose, but don't need the storage to be changed.

5173 MatAssemblyBegin - Begins assembling the matrix. This routine should

5175
5176 Collective on Mat
5177
5178 Input Parameters:
5179+ mat - the matrix
5180- type - type of assembly, either MAT_FLUSH_ASSEMBLY or MAT_FINAL_ASSEMBLY
5181
5182 Notes:
5183 MatSetValues() generally caches the values. The matrix is ready to
5184 use only after MatAssemblyBegin() and MatAssemblyEnd() have been called.
5185 Use MAT_FLUSH_ASSEMBLY when switching between ADD_VALUES and INSERT_VALUES
5186 in MatSetValues(); use MAT_FINAL_ASSEMBLY for the final assembly before
5187 using the matrix.
5188
5189 ALL processes that share a matrix MUST call MatAssemblyBegin() and MatAssemblyEnd() the SAME NUMBER of times, and each time with the
5190 same flag of MAT_FLUSH_ASSEMBLY or MAT_FINAL_ASSEMBLY for all processes. Thus you CANNOT locally change from ADD_VALUES to INSERT_VALUES, that is
5191 a global collective operation requring all processes that share the matrix.
5192
5193 Space for preallocated nonzeros that is not filled by a call to MatSetValues() or a related routine are compressed
5194 out by assembly. If you intend to use that extra space on a subsequent assembly, be sure to insert explicit zeros
5195 before MAT_FINAL_ASSEMBLY so the space is not compressed out.

5350 MatSetOption - Sets a parameter option for a matrix. Some options
5351 may be specific to certain storage formats. Some options
5352 determine how values will be inserted (or added). Sorted,
5353 row-oriented input will generally assemble the fastest. The default
5354 is row-oriented.
5355
5356 Logically Collective on Mat for certain operations, such as MAT_SPD, not collective for MAT_ROW_ORIENTED, see MatOption
5357
5358 Input Parameters:
5359+ mat - the matrix
5360. option - the option, one of those listed below (and possibly others),
5361- flg - turn the option on (PETSC_TRUE) or off (PETSC_FALSE)
5362
5363 Options Describing Matrix Structure:
5364+ MAT_SPD - symmetric positive definite
5365. MAT_SYMMETRIC - symmetric in terms of both structure and value
5366. MAT_HERMITIAN - transpose is the complex conjugation
5367. MAT_STRUCTURALLY_SYMMETRIC - symmetric nonzero structure
5368- MAT_SYMMETRY_ETERNAL - if you would like the symmetry/Hermitian flag
5369 you set to be kept with all future use of the matrix
5370 including after MatAssemblyBegin/End() which could
5371 potentially change the symmetry structure, i.e. you
5372 KNOW the matrix will ALWAYS have the property you set.
5373
5374
5375 Options For Use with MatSetValues():
5376 Insert a logically dense subblock, which can be
5377. MAT_ROW_ORIENTED - row-oriented (default)
5378
5379 Note these options reflect the data you pass in with MatSetValues(); it has
5380 nothing to do with how the data is stored internally in the matrix
5381 data structure.
5382
5383 When (re)assembling a matrix, we can restrict the input for
5384 efficiency/debugging purposes. These options include:
5385+ MAT_NEW_NONZERO_LOCATIONS - additional insertions will be allowed if they generate a new nonzero (slow)
5386. MAT_NEW_DIAGONALS - new diagonals will be allowed (for block diagonal format only)
5387. MAT_IGNORE_OFF_PROC_ENTRIES - drops off-processor entries
5388. MAT_NEW_NONZERO_LOCATION_ERR - generates an error for new matrix entry
5389. MAT_USE_HASH_TABLE - uses a hash table to speed up matrix assembly
5390. MAT_NO_OFF_PROC_ENTRIES - you know each process will only set values for its own rows, will generate an error if
5391 any process sets values for another process. This avoids all reductions in the MatAssembly routines and thus improves
5392 performance for very large process counts.
5393- MAT_SUBSET_OFF_PROC_ENTRIES - you know that the first assembly after setting this flag will set a superset
5394 of the off-process entries required for all subsequent assemblies. This avoids a rendezvous step in the MatAssembly
5395 functions, instead sending only neighbor messages.
5396
5397 Notes:
5398 Except for MAT_UNUSED_NONZERO_LOCATION_ERR and MAT_ROW_ORIENTED all processes that share the matrix must pass the same value in flg!
5399
5400 Some options are relevant only for particular matrix types and
5401 are thus ignored by others. Other options are not supported by
5402 certain matrix types and will generate an error message if set.
5403
5404 If using a Fortran 77 module to compute a matrix, one may need to
5405 use the column-oriented option (or convert to the row-oriented
5406 format).
5407
5408 MAT_NEW_NONZERO_LOCATIONS set to PETSC_FALSE indicates that any add or insertion
5409 that would generate a new entry in the nonzero structure is instead
5410 ignored. Thus, if memory has not alredy been allocated for this particular
5411 data, then the insertion is ignored. For dense matrices, in which
5412 the entire array is allocated, no entries are ever ignored.
5413 Set after the first MatAssemblyEnd(). If this option is set then the MatAssemblyBegin/End() processes has one less global reduction
5414
5415 MAT_NEW_NONZERO_LOCATION_ERR set to PETSC_TRUE indicates that any add or insertion
5416 that would generate a new entry in the nonzero structure instead produces
5417 an error. (Currently supported for AIJ and BAIJ formats only.) If this option is set then the MatAssemblyBegin/End() processes has one less global reduction
5418
5419 MAT_NEW_NONZERO_ALLOCATION_ERR set to PETSC_TRUE indicates that any add or insertion
5420 that would generate a new entry that has not been preallocated will
5421 instead produce an error. (Currently supported for AIJ and BAIJ formats
5422 only.) This is a useful flag when debugging matrix memory preallocation.
5423 If this option is set then the MatAssemblyBegin/End() processes has one less global reduction
5424
5425 MAT_IGNORE_OFF_PROC_ENTRIES set to PETSC_TRUE indicates entries destined for
5426 other processors should be dropped, rather than stashed.
5427 This is useful if you know that the "owning" processor is also
5428 always generating the correct matrix entries, so that PETSc need
5429 not transfer duplicate entries generated on another processor.
5430
5431 MAT_USE_HASH_TABLE indicates that a hash table be used to improve the
5432 searches during matrix assembly. When this flag is set, the hash table
5433 is created during the first Matrix Assembly. This hash table is
5434 used the next time through, during MatSetVaules()/MatSetVaulesBlocked()
5435 to improve the searching of indices. MAT_NEW_NONZERO_LOCATIONS flag
5436 should be used with MAT_USE_HASH_TABLE flag. This option is currently
5437 supported by MATMPIBAIJ format only.
5438
5439 MAT_KEEP_NONZERO_PATTERN indicates when MatZeroRows() is called the zeroed entries
5440 are kept in the nonzero structure
5441
5442 MAT_IGNORE_ZERO_ENTRIES - for AIJ/IS matrices this will stop zero values from creating
5443 a zero location in the matrix
5444
5445 MAT_USE_INODES - indicates using inode version of the code - works with AIJ matrix types
5446
5447 MAT_NO_OFF_PROC_ZERO_ROWS - you know each process will only zero its own rows. This avoids all reductions in the
5448 zero row routines and thus improves performance for very large process counts.
5449
5450 MAT_IGNORE_LOWER_TRIANGULAR - For SBAIJ matrices will ignore any insertions you make in the lower triangular
5451 part of the matrix (since they should match the upper triangular part).
5452
5453 MAT_SORTED_FULL - each process provides exactly its local rows; all column indices for a given row are passed in a
5454 single call to MatSetValues(), preallocation is perfect, row oriented, INSERT_VALUES is used. Common
5455 with finite difference schemes with non-periodic boundary conditions.
5456 Notes:
5457 Can only be called after MatSetSizes() and MatSetType() have been set.

5650
5651 Collective on Mat
5652
5653 Input Parameters:
5654+ mat - the matrix
5655. numRows - the number of rows to remove
5656. rows - the global row indices
5657. diag - value put in all diagonals of eliminated rows (0.0 will even eliminate diagonal entry)
5658. x - optional vector of solutions for zeroed rows (other entries in vector are not used)
5659- b - optional vector of right hand side, that will be adjusted by provided solution
5660
5661 Notes:
5662 This does not change the nonzero structure of the matrix, it merely zeros those entries in the matrix.
5663
5664 The user can set a value in the diagonal entry (or for the AIJ and
5665 row formats can optionally remove the main diagonal entry from the
5666 nonzero structure as well, by passing 0.0 as the final argument).
5667
5668 For the parallel case, all processes that share the matrix (i.e.,
5669 those in the communicator used for matrix creation) MUST call this
5670 routine, regardless of whether any rows being zeroed are owned by
5671 them.
5672
5673 Each processor can indicate any rows in the entire matrix to be zeroed (i.e. each process does NOT have to
5674 list only rows local to itself).
5675
5676 The option MAT_NO_OFF_PROC_ZERO_ROWS does not apply to this routine.

5761 MatZeroRows - Zeros all entries (except possibly the main diagonal)
5762 of a set of rows of a matrix.
5763
5764 Collective on Mat
5765
5766 Input Parameters:
5767+ mat - the matrix
5768. numRows - the number of rows to remove
5769. rows - the global row indices
5770. diag - value put in all diagonals of eliminated rows (0.0 will even eliminate diagonal entry)
5771. x - optional vector of solutions for zeroed rows (other entries in vector are not used)
5772- b - optional vector of right hand side, that will be adjusted by provided solution
5773
5774 Notes:
5775 For the AIJ and BAIJ matrix formats this removes the old nonzero structure,
5776 but does not release memory. For the dense and block diagonal
5777 formats this does not alter the nonzero structure.
5778
5779 If the option MatSetOption(mat,MAT_KEEP_NONZERO_PATTERN,PETSC_TRUE) the nonzero structure
5780 of the matrix is not changed (even for AIJ and BAIJ matrices) the values are
5781 merely zeroed.
5782
5783 The user can set a value in the diagonal entry (or for the AIJ and
5784 row formats can optionally remove the main diagonal entry from the
5785 nonzero structure as well, by passing 0.0 as the final argument).
5786
5787 For the parallel case, all processes that share the matrix (i.e.,
5788 those in the communicator used for matrix creation) MUST call this
5789 routine, regardless of whether any rows being zeroed are owned by
5790 them.
5791
5792 Each processor can indicate any rows in the entire matrix to be zeroed (i.e. each process does NOT have to
5793 list only rows local to itself).
5794
5795 You can call MatSetOption(mat,MAT_NO_OFF_PROC_ZERO_ROWS,PETSC_TRUE) if each process indicates only rows it
5796 owns that are to be zeroed. This saves a global synchronization in the implementation.

5923 In Fortran idxm and idxn should be declared as
5924$ MatStencil idxm(4,m)

5929$ idxm(MatStencil_c,1) = c
5930 etc
5931
5932 For periodic boundary conditions use negative indices for values to the left (below 0; that are to be
5933 obtained by wrapping values from right edge). For values to the right of the last entry using that index plus one
5934 etc to obtain values that obtained by wrapping the values from the left edge. This does not work for anything but the
5935 DM_BOUNDARY_PERIODIC boundary type.
5936
5937 For indices that don't mean anything for your case (like the k index when working in 2d) or the c index when you have
5938 a single value per point) you can skip filling those indices.

5986 MatZeroRowsColumnsStencil - Zeros all row and column entries (except possibly the main diagonal)
5987 of a set of rows and columns of a matrix.
5988
5989 Collective on Mat
5990
5991 Input Parameters:
5992+ mat - the matrix
5993. numRows - the number of rows/columns to remove
5994. rows - the grid coordinates (and component number when dof > 1) for matrix rows
5995. diag - value put in all diagonals of eliminated rows (0.0 will even eliminate diagonal entry)
5996. x - optional vector of solutions for zeroed rows (other entries in vector are not used)
5997- b - optional vector of right hand side, that will be adjusted by provided solution
5998
5999 Notes:
6000 For the AIJ and BAIJ matrix formats this removes the old nonzero structure,
6001 but does not release memory. For the dense and block diagonal
6002 formats this does not alter the nonzero structure.
6003
6004 If the option MatSetOption(mat,MAT_KEEP_NONZERO_PATTERN,PETSC_TRUE) the nonzero structure
6005 of the matrix is not changed (even for AIJ and BAIJ matrices) the values are
6006 merely zeroed.
6007
6008 The user can set a value in the diagonal entry (or for the AIJ and
6009 row formats can optionally remove the main diagonal entry from the
6010 nonzero structure as well, by passing 0.0 as the final argument).
6011
6012 For the parallel case, all processes that share the matrix (i.e.,
6013 those in the communicator used for matrix creation) MUST call this
6014 routine, regardless of whether any rows being zeroed are owned by
6015 them.
6016
6017 Each processor can indicate any rows in the entire matrix to be zeroed (i.e. each process does NOT have to
6018 list only rows local to itself, but the row/column numbers are given in local numbering).
6019
6020 The grid coordinates are across the entire grid, not just the local portion
6021
6022 In Fortran idxm and idxn should be declared as
6023$ MatStencil idxm(4,m)
6024 and the values inserted using
6025$ idxm(MatStencil_i,1) = i
6026$ idxm(MatStencil_j,1) = j
6027$ idxm(MatStencil_k,1) = k
6028$ idxm(MatStencil_c,1) = c
6029 etc
6030
6031 For periodic boundary conditions use negative indices for values to the left (below 0; that are to be
6032 obtained by wrapping values from right edge). For values to the right of the last entry using that index plus one
6033 etc to obtain values that obtained by wrapping the values from the left edge. This does not work for anything but the
6034 DM_BOUNDARY_PERIODIC boundary type.
6035
6036 For indices that don't mean anything for your case (like the k index when working in 2d) or the c index when you have
6037 a single value per point) you can skip filling those indices.

6085 MatZeroRowsLocal - Zeros all entries (except possibly the main diagonal)
6086 of a set of rows of a matrix; using local numbering of rows.
6087
6088 Collective on Mat
6089
6090 Input Parameters:
6091+ mat - the matrix
6092. numRows - the number of rows to remove
6093. rows - the global row indices
6094. diag - value put in all diagonals of eliminated rows
6095. x - optional vector of solutions for zeroed rows (other entries in vector are not used)
6096- b - optional vector of right hand side, that will be adjusted by provided solution
6097
6098 Notes:
6099 Before calling MatZeroRowsLocal(), the user must first set the
6100 local-to-global mapping by calling MatSetLocalToGlobalMapping().
6101
6102 For the AIJ matrix formats this removes the old nonzero structure,
6103 but does not release memory. For the dense and block diagonal
6104 formats this does not alter the nonzero structure.
6105
6106 If the option MatSetOption(mat,MAT_KEEP_NONZERO_PATTERN,PETSC_TRUE) the nonzero structure
6107 of the matrix is not changed (even for AIJ and BAIJ matrices) the values are
6108 merely zeroed.
6109
6110 The user can set a value in the diagonal entry (or for the AIJ and
6111 row formats can optionally remove the main diagonal entry from the
6112 nonzero structure as well, by passing 0.0 as the final argument).
6113
6114 You can call MatSetOption(mat,MAT_NO_OFF_PROC_ZERO_ROWS,PETSC_TRUE) if each process indicates only rows it
6115 owns that are to be zeroed. This saves a global synchronization in the implementation.

6159 MatZeroRowsLocalIS - Zeros all entries (except possibly the main diagonal)
6160 of a set of rows of a matrix; using local numbering of rows.
6161
6162 Collective on Mat
6163
6164 Input Parameters:
6165+ mat - the matrix
6166. is - index set of rows to remove
6167. diag - value put in all diagonals of eliminated rows
6168. x - optional vector of solutions for zeroed rows (other entries in vector are not used)
6169- b - optional vector of right hand side, that will be adjusted by provided solution
6170
6171 Notes:
6172 Before calling MatZeroRowsLocalIS(), the user must first set the
6173 local-to-global mapping by calling MatSetLocalToGlobalMapping().
6174
6175 For the AIJ matrix formats this removes the old nonzero structure,
6176 but does not release memory. For the dense and block diagonal
6177 formats this does not alter the nonzero structure.
6178
6179 If the option MatSetOption(mat,MAT_KEEP_NONZERO_PATTERN,PETSC_TRUE) the nonzero structure
6180 of the matrix is not changed (even for AIJ and BAIJ matrices) the values are
6181 merely zeroed.
6182
6183 The user can set a value in the diagonal entry (or for the AIJ and
6184 row formats can optionally remove the main diagonal entry from the
6185 nonzero structure as well, by passing 0.0 as the final argument).
6186
6187 You can call MatSetOption(mat,MAT_NO_OFF_PROC_ZERO_ROWS,PETSC_TRUE) if each process indicates only rows it
6188 owns that are to be zeroed. This saves a global synchronization in the implementation.

6558 Output Parameters:
6559. fact - new matrix that has been symbolically factored
6560
6561 Notes:
6562 See Users-Manual: ch_mat for additional information about choosing the fill factor for better efficiency.

6670/*@C
6671 MatCreateSubMatrices - Extracts several submatrices from a matrix. If submat
6672 points to an array of valid matrices, they may be reused to store the new
6673 submatrices.
6674
6675 Collective on Mat
6676
6677 Input Parameters:
6678+ mat - the matrix
6679. n - the number of submatrixes to be extracted (on this processor, may be zero)
6680. irow, icol - index sets of rows and columns to extract
6681- scall - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX
6682
6683 Output Parameter:
6684. submat - the array of submatrices
6685
6686 Notes:
6687 MatCreateSubMatrices() can extract ONLY sequential submatrices
6688 (from both sequential and parallel matrices). Use MatCreateSubMatrix()
6689 to extract a parallel submatrix.
6690
6691 Some matrix types place restrictions on the row and column
6692 indices, such as that they be sorted or that they be equal to each other.
6693
6694 The index sets may not have duplicate entries.
6695
6696 When extracting submatrices from a parallel matrix, each processor can
6697 form a different submatrix by setting the rows and columns of its
6698 individual index sets according to the local submatrix desired.
6699
6700 When finished using the submatrices, the user should destroy
6701 them with MatDestroySubMatrices().
6702
6703 MAT_REUSE_MATRIX can only be used when the nonzero structure of the
6704 original matrix has not changed from that last call to MatCreateSubMatrices().
6705
6706 This routine creates the matrices in submat; you should NOT create them before
6707 calling it. It also allocates the array of matrix pointers submat.
6708
6709 For BAIJ matrices the index sets must respect the block structure, that is if they
6710 request one row/column in a block, they must request all rows/columns that are in
6711 that block. For example, if the block size is 2 you cannot request just row 0 and
6712 column 0.
6713
6714 Fortran Note:
6715 The Fortran interface is slightly different from that given below; it
6716 requires one to pass in as submat a Mat (integer) array of size at least n+1.

7220 MatSetBlockSizes - Sets the matrix block row and column sizes.
7221
7222 Logically Collective on Mat
7223
7224 Input Parameters:
7225+ mat - the matrix
7226- rbs - row block size
7227- cbs - column block size
7228
7229 Notes:
7230 Block row formats are MATSEQBAIJ, MATMPIBAIJ, MATSEQSBAIJ, MATMPISBAIJ. These formats ALWAYS have square block storage in the matrix.
7231 If you pass a different block size for the columns than the rows, the row block size determines the square block storage.
7232 This must be called before MatSetUp() or MatXXXSetPreallocation() (or will default to 1) and the block size cannot be changed later
7233
7234 For MATMPIAIJ and MATSEQAIJ matrix formats, this function can be called at a later stage, provided that the specified block sizes
7235 are compatible with the matrix local sizes.
7236
7237 The row and column block size determine the blocksize of the "row" and "column" vectors returned by MatCreateVecs().

7349/*@C
7350 MatGetRowIJ - Returns the compressed row storage i and j indices for sequential matrices.
7351
7352 Collective on Mat
7353
7354 Input Parameters:
7355+ mat - the matrix
7356. shift - 0 or 1 indicating we want the indices starting at 0 or 1
7357. symmetric - PETSC_TRUE or PETSC_FALSE indicating the matrix data structure should be symmetrized
7358- inodecompressed - PETSC_TRUE or PETSC_FALSE indicating if the nonzero structure of the
7359 inodes or the nonzero elements is wanted. For BAIJ matrices the compressed version is
7360 always used.
7361
7362 Output Parameters:
7363+ n - number of rows in the (possibly compressed) matrix
7364. ia - the row pointers; that is ia[0] = 0, ia[row] = ia[row-1] + number of elements in that row of the matrix
7365. ja - the column indices
7366- done - indicates if the routine actually worked and returned appropriate ia[] and ja[] arrays; callers
7367 are responsible for handling the case when done == PETSC_FALSE and ia and ja are not set
7368
7369 Level: developer
7370
7371 Notes:
7372 You CANNOT change any of the ia[] or ja[] values.
7373
7374 Use MatRestoreRowIJ() when you are finished accessing the ia[] and ja[] values.

7480 This routine zeros out n, ia, and ja. This is to prevent accidental
7481 us of the array after it has been restored. If you pass NULL, it will
7482 not zero the pointers. Use of ia or ja after MatRestoreRowIJ() is invalid.

7600 MatSetUnfactored - Resets a factored matrix to be treated as unfactored.
7601
7602 Logically Collective on Mat
7603
7604 Input Parameter:
7605. mat - the factored matrix to be reset
7606
7607 Notes:
7608 This routine should be used only with factored matrices formed by in-place
7609 factorization via ILU(0) (or by in-place LU factorization for the MATSEQDENSE
7610 format). This option can save memory, for example, when solving nonlinear
7611 systems with a matrix-free Newton-Krylov method and a matrix-based, in-place
7612 ILU(0) preconditioner.
7613
7614 Note that one can specify in-place ILU(0) factorization by calling
7615.vb
7616 PCType(pc,PCILU);
7617 PCFactorSeUseInPlace(pc);
7618.ve
7619 or by using the options -pc_type ilu -pc_factor_in_place
7620
7621 In-place factorization ILU(0) can also be used as a local
7622 solver for the blocks within the block Jacobi or additive Schwarz
7623 methods (runtime option: -sub_pc_factor_in_place). See Users-Manual: ch_pc
7624 for details on setting local solver options.
7625
7626 Most users should employ the simplified KSP interface for linear solvers
7627 instead of working directly with matrix algebra routines such as this.
7628 See, e.g., KSPCreate().

7774 MatCreateSubMatrix - Gets a single submatrix on the same number of processors
7775 as the original matrix.
7776
7777 Collective on Mat
7778
7779 Input Parameters:
7780+ mat - the original matrix
7781. isrow - parallel IS containing the rows this processor should obtain
7782. iscol - parallel IS containing all columns you wish to keep. Each process should list the columns that will be in IT's "diagonal part" in the new matrix.
7783- cll - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX
7784
7785 Output Parameter:
7786. newmat - the new submatrix, of the same type as the old
7787
7788 Level: advanced
7789
7790 Notes:
7791 The submatrix will be able to be multiplied with vectors using the same layout as iscol.
7792
7793 Some matrix types place restrictions on the row and column indices, such
7794 as that they be sorted or that they be equal to each other.
7795
7796 The index sets may not have duplicate entries.
7797
7798 The first time this is called you should use a cll of MAT_INITIAL_MATRIX,
7799 the MatCreateSubMatrix() routine will create the newmat for you. Any additional calls
7800 to this routine with a mat of the same nonzero structure and with a call of MAT_REUSE_MATRIX
7801 will reuse the matrix generated the first time. You should call MatDestroy() on newmat when
7802 you are finished using it.
7803
7804 The communicator of the newly obtained matrix is ALWAYS the same as the communicator of
7805 the input matrix.
7806
7807 If iscol is NULL then all columns are obtained (not supported in Fortran).
7808
7809 Example usage:
7810 Consider the following 8x8 matrix with 34 non-zero values, that is
7811 assembled across 3 processors. Let's assume that proc0 owns 3 rows,
7812 proc1 owns 3 rows, proc2 owns 2 rows. This division can be shown
7813 as follows:

8144 Input Parameters:
8145+ mat - the matrix
8146- nullsp - the null space object
8147
8148 Level: advanced
8149
8150 Notes:
8151 This null space is used by the linear solvers. Overwrites any previous null space that may have been attached
8152
8153 For inconsistent singular systems (linear systems where the right hand side is not in the range of the operator) you also likely should
8154 call MatSetTransposeNullSpace(). This allows the linear system to be solved in a least squares sense.
8155
8156 You can remove the null space by calling this routine with an nullsp of NULL
8157
8158
8159 The fundamental theorem of linear algebra (Gilbert Strang, Introduction to Applied Mathematics, page 72) states that
8160 the domain of a matrix A (from R^n to R^m (m rows, n columns) R^n = the direct sum of the null space of A, n(A), + the range of A^T, R(A^T).
8161 Similarly R^m = direct sum n(A^T) + R(A). Hence the linear system A x = b has a solution only if b in R(A) (or correspondingly b is orthogonal to
8162 n(A^T)) and if x is a solution then x + alpha n(A) is a solution for any alpha. The minimum norm solution is orthogonal to n(A). For problems without a solution
8163 the solution that minimizes the norm of the residual (the least squares solution) can be obtained by solving A x = \hat{b} where \hat{b} is b orthogonalized to the n(A^T).
8164
8165 Krylov solvers can produce the minimal norm solution to the least squares problem by utilizing MatNullSpaceRemove().
8166
8167 If the matrix is known to be symmetric because it is an SBAIJ matrix or one as called MatSetOption(mat,MAT_SYMMETRIC or MAT_SYMMETRIC_ETERNAL,PETSC_TRUE); this
8168 routine also automatically calls MatSetTransposeNullSpace().

8212 MatSetTransposeNullSpace - attaches a null space to a matrix.

8217+ mat - the matrix
8218- nullsp - the null space object
8219

8221
8222 Notes:
8223 For inconsistent singular systems (linear systems where the right hand side is not in the range of the operator) this allows the linear system to be solved in a least squares sense.
8224 You must also call MatSetNullSpace()
8225
8226
8227 The fundamental theorem of linear algebra (Gilbert Strang, Introduction to Applied Mathematics, page 72) states that
8228 the domain of a matrix A (from R^n to R^m (m rows, n columns) R^n = the direct sum of the null space of A, n(A), + the range of A^T, R(A^T).
8229 Similarly R^m = direct sum n(A^T) + R(A). Hence the linear system A x = b has a solution only if b in R(A) (or correspondingly b is orthogonal to
8230 n(A^T)) and if x is a solution then x + alpha n(A) is a solution for any alpha. The minimum norm solution is orthogonal to n(A). For problems without a solution
8231 the solution that minimizes the norm of the residual (the least squares solution) can be obtained by solving A x = \hat{b} where \hat{b} is b orthogonalized to the n(A^T).
8232
8233 Krylov solvers can produce the minimal norm solution to the least squares problem by utilizing MatNullSpaceRemove().

8853 MatFactorCreateSchurComplement - Create a Schur complement matrix object using Schur data computed during the factorization step
8854
8855 Logically Collective on Mat
8856
8857 Input Parameters:
8858+ F - the factored matrix obtained by calling MatGetFactor() from PETSc-MUMPS interface
8859. S - location where to return the Schur complement, can be NULL
8860- status - the status of the Schur complement matrix, can be NULL
8861
8862 Notes:
8863 You must call MatFactorSetSchurIS() before calling this routine.
8864
8865 The routine provides a copy of the Schur matrix stored within the solver data structures.
8866 The caller must destroy the object when it is no longer needed.
8867 If MatFactorInvertSchurComplement() has been called, the routine gets back the inverse.
8868
8869 Use MatFactorGetSchurComplement() to get access to the Schur complement matrix inside the factored matrix instead of making a copy of it (which this function does)
8870
8871 Developer Notes:
8872 The reason this routine exists is because the representation of the Schur complement within the factor matrix may be different than a standard PETSc
8873 matrix representation and we normally do not want to use the time or memory to make a copy as a regular PETSc matrix.
8874
8875 See MatCreateSchurComplement() or MatGetSchurComplement() for ways to create virtual or approximate Schur complements.

8911+ F - the factored matrix obtained by calling MatGetFactor()
8912. *S - location where to return the Schur complement, can be NULL
8913- status - the status of the Schur complement matrix, can be NULL

8915 Notes:
8916 You must call MatFactorSetSchurIS() before calling this routine.
8917
8918 Schur complement mode is currently implemented for sequential matrices.
8919 The routine returns a the Schur Complement stored within the data strutures of the solver.
8920 If MatFactorInvertSchurComplement() has previously been called, the returned matrix is actually the inverse of the Schur complement.
8921 The returned matrix should not be destroyed; the caller should call MatFactorRestoreSchurComplement() when the object is no longer needed.

9151/*@
9152 MatPtAP - Creates the matrix product C = P^T * A * P
9153
9154 Neighbor-wise Collective on Mat
9155
9156 Input Parameters:
9157+ A - the matrix
9158. P - the projection matrix
9159. scall - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX
9160- fill - expected fill as ratio of nnz(C)/(nnz(A) + nnz(P)), use PETSC_DEFAULT if you do not have a good estimate
9161 if the result is a dense matrix this is irrelevent
9162
9163 Output Parameters:
9164. C - the product matrix
9165
9166 Notes:
9167 C will be created and must be destroyed by the user with MatDestroy().
9168
9169 For matrix types without special implementation the function fallbacks to MatMatMult() followed by MatTransposeMatMult().

9354 MatRARt - Creates the matrix product C = R * A * R^T
9355
9356 Neighbor-wise Collective on Mat
9357
9358 Input Parameters:
9359+ A - the matrix
9360. R - the projection matrix
9361. scall - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX
9362- fill - expected fill as ratio of nnz(C)/nnz(A), use PETSC_DEFAULT if you do not have a good estimate
9363 if the result is a dense matrix this is irrelevent
9364
9365 Output Parameters:
9366. C - the product matrix
9367
9368 Notes:
9369 C will be created and must be destroyed by the user with MatDestroy().
9370
9371 This routine is currently only implemented for pairs of AIJ matrices and classes
9372 which inherit from AIJ. Due to PETSc sparse matrix block row distribution among processes,
9373 parallel MatRARt is implemented via explicit transpose of R, which could be very expensive.
9374 We recommend using MatPtAP().

9520 MatMatMult - Performs Matrix-Matrix Multiplication C=A*B.
9521
9522 Neighbor-wise Collective on Mat
9523
9524 Input Parameters:
9525+ A - the left matrix
9526. B - the right matrix
9527. scall - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX
9528- fill - expected fill as ratio of nnz(C)/(nnz(A) + nnz(B)), use PETSC_DEFAULT if you do not have a good estimate
9529 if the result is a dense matrix this is irrelevent
9530
9531 Output Parameters:
9532. C - the product matrix
9533
9534 Notes:
9535 Unless scall is MAT_REUSE_MATRIX C will be created.
9536
9537 MAT_REUSE_MATRIX can only be used if the matrices A and B have the same nonzero pattern as in the previous call and C was obtained from a previous
9538 call to this function with either MAT_INITIAL_MATRIX or MatMatMultSymbolic()
9539
9540 To determine the correct fill value, run with -info and search for the string "Fill ratio" to see the value
9541 actually needed.
9542
9543 If you have many matrices with the same non-zero structure to multiply, you
9544 should either
9545$ 1) use MAT_REUSE_MATRIX in all calls but the first or
9546$ 2) call MatMatMultSymbolic() once and then MatMatMultNumeric() for each product needed
9547 In the special case where matrix B (and hence C) are dense you can create the correctly sized matrix C yourself and then call this routine
9548 with MAT_REUSE_MATRIX, rather than first having MatMatMult() create it for you. You can NEVER do this if the matrix C is sparse.

9626 MatMatMultSymbolic - Performs construction, preallocation, and computes the ij structure
9627 of the matrix-matrix product C=A*B. Call this routine before calling MatMatMultNumeric().
9628
9629 Neighbor-wise Collective on Mat
9630
9631 Input Parameters:
9632+ A - the left matrix
9633. B - the right matrix
9634- fill - expected fill as ratio of nnz(C)/(nnz(A) + nnz(B)), use PETSC_DEFAULT if you do not have a good estimate,
9635 if C is a dense matrix this is irrelevent
9636
9637 Output Parameters:
9638. C - the product matrix
9639
9640 Notes:
9641 To determine the correct fill value, run with -info and search for the string "Fill ratio" to see the value
9642 actually needed.
9643
9644 This routine is currently implemented for
9645 - pairs of AIJ matrices and classes which inherit from AIJ, C will be of type AIJ
9646 - pairs of AIJ (A) and Dense (B) matrix, C will be of type Dense.
9647 - pairs of Dense (A) and AIJ (B) matrix, C will be of type Dense.
9648
9649 Level: intermediate
9650
9651 Developers Note: There are ways to estimate the number of nonzeros in the resulting product, see for example, https://arxiv.org/abs/1006.4173
9652 We should incorporate them into PETSc.

9821 MatTransposeMatMult - Performs Matrix-Matrix Multiplication C=A^T*B.
9822
9823 Neighbor-wise Collective on Mat
9824
9825 Input Parameters:
9826+ A - the left matrix
9827. B - the right matrix
9828. scall - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX
9829- fill - expected fill as ratio of nnz(C)/(nnz(A) + nnz(B)), use PETSC_DEFAULT if not known
9830
9831 Output Parameters:
9832. C - the product matrix
9833
9834 Notes:
9835 C will be created if MAT_INITIAL_MATRIX and must be destroyed by the user with MatDestroy().
9836
9837 MAT_REUSE_MATRIX can only be used if the matrices A and B have the same nonzero pattern as in the previous call
9838
9839 To determine the correct fill value, run with -info and search for the string "Fill ratio" to see the value
9840 actually needed.
9841
9842 This routine is currently implemented for pairs of AIJ matrices and pairs of SeqDense matrices and classes
9843 which inherit from SeqAIJ. C will be of same type as the input matrices.

9998 MatCreateRedundantMatrix - Create redundant matrices and put them into processors of subcommunicators.
9999
10000 Collective on Mat
10001
10002 Input Parameters:
10003+ mat - the matrix
10004. nsubcomm - the number of subcommunicators (= number of redundant parallel or sequential matrices)
10005. subcomm - MPI communicator split from the communicator where mat resides in (or MPI_COMM_NULL if nsubcomm is used)
10006- reuse - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX
10007
10008 Output Parameter:
10009. matredundant - redundant matrix
10010
10011 Notes:
10012 MAT_REUSE_MATRIX can only be used when the nonzero structure of the
10013 original matrix has not changed from that last call to MatCreateRedundantMatrix().
10014
10015 This routine creates the duplicated matrices in subcommunicators; you should NOT create them before
10016 calling it.

10122/*@C
10123 MatGetMultiProcBlock - Create multiple [bjacobi] 'parallel submatrices' from
10124 a given 'mat' object. Each submatrix can span multiple procs.
10125
10126 Collective on Mat
10127
10128 Input Parameters:
10129+ mat - the matrix
10130. subcomm - the subcommunicator obtained by com_split(comm)
10131- scall - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX
10132
10133 Output Parameter:
10134. subMat - 'parallel submatrices each spans a given subcomm
10135
10136 Notes:
10137 The submatrix partition across processors is dictated by 'subComm' a
10138 communicator obtained by com_split(comm). The comm_split
10139 is not restriced to be grouped with consecutive original ranks.
10140
10141 Due the comm_split() usage, the parallel layout of the submatrices
10142 map directly to the layout of the original matrix [wrt the local
10143 row,col partitioning]. So the original 'DiagonalMat' naturally maps
10144 into the 'DiagonalMat' of the subMat, hence it is used directly from
10145 the subMat. However the offDiagMat looses some columns - and this is
10146 reconstructed with MatSetValues()

10183 Level: intermediate
10184
10185 Notes:
10186 The submat should be returned with MatRestoreLocalSubMatrix().
10187
10188 Depending on the format of mat, the returned submat may not implement MatMult(). Its communicator may be
10189 the same as mat, it may be PETSC_COMM_SELF, or some other subcomm of mat's.
10190
10191 The submat always implements MatSetValuesLocal(). If isrow and iscol have the same block size, then
10192 MatSetValuesBlockedLocal() will also be implemented.
10193
10194 The mat must have had a ISLocalToGlobalMapping provided to it with MatSetLocalToGlobalMapping(). Note that
10195 matrices obtained with DMCreateMatrix() generally already have the local to global mapping provided.

10775 Notes:
10776 See the file include/petscmat.h for a complete list of matrix
10777 operations, which all have the form MATOP_<OPERATION>, where
10778 <OPERATION> is the name (in all capital letters) of the
10779 user interface routine (e.g., MatMult() -> MATOP_MULT).
10780
10781 All user-provided functions (except for MATOP_DESTROY) should have the same calling
10782 sequence as the usual matrix interface routines, since they

10784 routines, e.g.,
10785$ MatMult(Mat,Vec,Vec) -> usermult(Mat,Vec,Vec)

10787 In particular each function MUST return an error code of 0 on success and
10788 nonzero on failure.
