This matrix inherits from MATAIJ. As a result, MatSeqAIJSetPreallocation() and MatMPIAIJSetPreallocation() are supported for this matrix type. One can also call MatConvert() for an inplace conversion to or from the MATAIJ type without data copy AFTER the matrix values have been set.
-mat_type aijspooles | - sets the matrix type to "aijspooles" during a call to MatSetFromOptions() | |
-mat_spooles_tau <tau> | - upper bound on the magnitude of the largest element in L or U | |
-mat_spooles_seed <seed> | - random number seed used for ordering | |
-mat_spooles_msglvl <msglvl> | - message output level | |
-mat_spooles_ordering <BestOfNDandMS,MMD,MS,ND> | - ordering used | |
-mat_spooles_maxdomainsize <n> | - maximum subgraph size used by Spooles orderings | |
-mat_spooles_maxzeros <n> | - maximum number of zeros inside a supernode | |
-mat_spooles_maxsize <n> | - maximum size of a supernode | |
-mat_spooles_FrontMtxInfo <true,fase> | - print Spooles information about the computed factorization | |
-mat_spooles_symmetryflag <0,1,2> | - 0: SPOOLES_SYMMETRIC, 1: SPOOLES_HERMITIAN, 2: SPOOLES_NONSYMMETRIC | |
-mat_spooles_patchAndGoFlag <0,1,2> | - 0: no patch, 1: use PatchAndGo strategy 1, 2: use PatchAndGo strategy 2 | |
-mat_spooles_toosmall <dt> | - drop tolerance for PatchAndGo strategy 1 | |
-mat_spooles_storeids <bool integer> | - if nonzero, stores row and col numbers where patches were applied in an IV object | |
-mat_spooles_fudge <delta> | - fudge factor for rescaling diagonals with PatchAndGo strategy 2 | |
-mat_spooles_storevalues <bool integer> | - if nonzero and PatchAndGo strategy 2 is used, store change in diagonal value in a DV object |
