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.
