MATORDERING_ND - Nested Dissection
MATORDERING_1WD - One-way Dissection
MATORDERING_RCM - Reverse Cuthill-McKee
MATORDERING_QMD - Quotient Minimum Degree
rperm | - row permutation indices | |
cperm | - column permutation indices |
-mat_ordering_type natural, -mat_ordering_type nd, -mat_ordering_type 1wd,
-mat_ordering_type rcm, -mat_ordering_type qmd
