MatUseScaledForm
For matrix storage formats that scale the matrix (for example MPIRowBS matrices are diagonally scaled on assembly) indicates matrix operations (MatMult() etc) are applied using the scaled matrix.
Synopsis
#include "petscmat.h"
int MatUseScaledForm(Mat mat,PetscTruth scaled)
Collective on Mat
Input Parameter
| mat | - the matrix
|
| scaled | - PETSC_TRUE for applying the scaled, PETSC_FALSE for
applying the original matrix
|
Notes
For scaled matrix formats, applying the original, unscaled matrix
will be slightly more expensive
