This matrix inherits from MATSEQAIJ. As a result, MatSeqAIJSetPreallocation is supported for this matrix type. One can also call MatConvert for an inplace conversion to or from the MATSEQAIJ type without data copy.
-mat_type superlu | - sets the matrix type to "superlu" during a call to MatSetFromOptions() | |
-mat_superlu_ordering <0,1,2,3> | - 0: natural ordering, 1: MMD applied to A'*A, 2: MMD applied to A'+A, 3: COLAMD, approximate minimum degree column ordering | |
-mat_superlu_iterrefine | - have SuperLU do iterative refinement after the triangular solve choices: NOREFINE, SINGLE, DOUBLE, EXTRA; default is NOREFINE | |
-mat_superlu_printstat | - print SuperLU statistics about the factorization |
