#include "petscpc.h" PetscErrorCode PETSCKSP_DLLEXPORT PCFactorSetMatOrderingType(PC pc,const MatOrderingType ordering)Collective on PC
pc | - the preconditioner context | |
ordering | - the matrix ordering name, for example, MATORDERING_ND or MATORDERING_RCM |
Notes: nested dissection is used by default
For Cholesky and ICC and the SBAIJ format reorderings are not available, since only the upper triangular part of the matrix is stored. You can use the SeqAIJ format in this case to get reorderings.
