Sets a flag indicating that during STSetUp the coefficient matrix of the KSP linear system (A) must be set to be the same matrix as the preconditioner (P). 
Synopsis
#include "slepcst.h" 
PetscErrorCode STPrecondSetKSPHasMat(ST st,PetscBool setmat)
Collective on ST
Input Parameter
|  | st | - the spectral transformation context | 
|  | setmat | - the flag | 
Notes
In most cases, the preconditioner matrix is used only in the PC object, but
in external solvers this matrix must be provided also as the A-matrix in
the KSP object.
