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.
| -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 |
