GMatDiagonalScaleConstrained
Scales a constrained matrix on the left and right by diagonal matrices that are stored as vectors. Either of the two scaling matrices can be PETSC_NULL.
Synopsis
#include "gvec.h"
int GMatDiagonalScaleConstrained(GMat mat, GVec l, GVec r)
Input Parameters
mat -The grid matrix to be scaled
l -The left scaling vector (or PETSC_NULL)
r -The right scaling vector (or PETSC_NULL)
Notes
GMatDiagonalScaleConstrained() computes A <- LAR, where
L = a diagonal matrix
R = a diagonal matrix
