Sets a flag indicating that during STSetUp the coefficient matrix of the KSP linear solver (A) must be set to be the same matrix as the preconditioner (P).
Synopsis
#include "slepcst.h"
PetscErrorCode STPrecondSetKSPHasMat(ST st,PetscBool ksphasmat)
Collective
Input Parameters
| st | - the spectral transformation context
|
| ksphasmat | - the flag

Notes
Often, the preconditioner matrix is used only in the PC object, but
in some solvers this matrix must be provided also as the A-matrix in
the KSP object.
