PCFactorSetMatSolverType#

sets the solver package that is used to perform the factorization

Synopsis#

#include "petscpc.h" 
PetscErrorCode PCFactorSetMatSolverType(PC pc, MatSolverType stype)

Logically Collective

Input Parameters#

pc - the preconditioner context
stype - for example, MATSOLVERSUPERLU, MATSOLVERSUPERLU_DIST, MATSOLVERMUMPS

Options Database Key#
