Scales a matrix on the left and right by diagonal matrices that are stored as vectors. Either of the two scaling matrices can be PETSC_NULL.
PetscErrorCode MatDiagonalScale(Mat mat,Vec l,Vec r)
Collective on Mat
|mat ||- the matrix to be scaled
|l ||- the left scaling vector (or PETSC_NULL)
|r ||- the right scaling vector (or PETSC_NULL)
MatDiagonalScale() computes A = LAR, where
L = a diagonal matrix (stored as a vector), R = a diagonal matrix (stored as a vector)
The L scales the rows of the matrix, the R scales the columns of the matrix.
