Synopsis#
#include "petscksp.h"
PetscErrorCode PCGalerkinGetKSP(PC pc, KSP *ksp)
Not Collective
Input Parameter#
pc - the preconditioner context
Output Parameter#
ksp - the
KSPobject
Note#
Once you have called this routine you can call KSPSetOperators() on the resulting KSP to provide the operator for the Galerkin problem,
an alternative is to use PCGalerkinSetComputeSubmatrix() to provide a routine that computes the submatrix as needed.
