STSetBalanceMatrix
Sets the diagonal matrix to be used for balancing.
Synopsis
#include "slepcst.h"
PetscErrorCode STSetBalanceMatrix(ST st,Vec D)
Collective
Input Parameters
| st | - the spectral transformation context
|
| D | - the diagonal matrix (represented as a vector)
|
Notes
If this matrix is set, STApply will effectively apply D*OP*D^{-1}. Use NULL
to reset a previously passed D.
Balancing is usually set via EPSSetBalance, but the advanced user may use
this function to bypass the usual balancing methods.
