3 Defines the basic matrix operations for the KAIJ matrix storage format.
4 This format is used to evaluate matrices of the form:
5
6 [I \otimes S + A \otimes T]
7
8 where
9 S is a dense (p \times q) matrix
10 T is a dense (p \times q) matrix
11 A is an AIJ (n \times n) matrix
12 I is the identity matrix
13
14 The resulting matrix is (np \times nq)
15
16 We provide:
17 MatMult()
18 MatMultAdd()
19 MatInvertBlockDiagonal()
20 and
21 MatCreateKAIJ(Mat,PetscInt,PetscInt,const PetscScalar[],const PetscScalar[],Mat*)
22
23 This single directory handles both the sequential and parallel codes

325 Input Parameters:
326+ A - the KAIJ matrix
327. p - the number of rows in S

1268/*@C
1269 MatCreateKAIJ - Creates a matrix type to be used for matrices of the following form:
1270
1271 [I \otimes S + A \otimes T]
1272
1273 where
1274 S is a dense (p \times q) matrix
1275 T is a dense (p \times q) matrix
1276 A is an AIJ (n \times n) matrix
1277 I is the identity matrix
1278 The resulting matrix is (np \times nq)
1279
1280 S and T are always stored independently on all processes as PetscScalar arrays in column-major format.
1281
1282 Collective
1283
1284 Input Parameters:
1285+ A - the AIJ matrix
1286. p - number of rows in S and T
1287. q - number of columns in S and T
1288. S - the S matrix (can be PETSC_NULL), stored as a PetscScalar array (column-major)
1289- T - the T matrix (can be PETSC_NULL), stored as a PetscScalar array (column-major)
1290
1291 Output Parameter:
1292. kaij - the new KAIJ matrix
1293
1294 Notes:
1295 This function increases the reference count on the AIJ matrix, so the user is free to destroy the matrix if it is not needed.
1296 Changes to the entries of the AIJ matrix will immediately affect the KAIJ matrix.

1323 MATKAIJ - MATKAIJ = "kaij" - A matrix type to be used to evaluate matrices of the following form:
1324
1325 [I \otimes S + A \otimes T]
1326
1327 where
1328 S is a dense (p \times q) matrix
1329 T is a dense (p \times q) matrix
1330 A is an AIJ (n \times n) matrix
1331 I is the identity matrix
1332 The resulting matrix is (np \times nq)
1333
1334 S and T are always stored independently on all processes as PetscScalar arrays in column-major format.
