STPrecondSetMatForPC
Sets the matrix that must be used to build the preconditioner.
Synopsis
#include "slepcst.h"
PetscErrorCode STPrecondSetMatForPC(ST st,Mat mat)
Logically Collective on ST and Mat
Input Parameter
| st | - the spectral transformation context
|
| mat | - the matrix that will be used in constructing the preconditioner
|
Notes
This matrix will be passed to the KSP object (via KSPSetOperators) as
the matrix to be used when constructing the preconditioner.
If no matrix is set or mat is set to NULL, A - sigma*B will
be used to build the preconditioner, being sigma the value set by STSetShift().
