MatDiagonalScale

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.

Synopsis

int MatDiagonalScale(Mat mat,Vec l,Vec r)
Collective on Mat

Input Parameters

mat - the matrix to be scaled
l - the left scaling vector (or PETSC_NULL)
r - the right scaling vector (or PETSC_NULL)

Notes

MatDiagonalScale() computes A = LAR, whereL = a diagonal matrix, R = a diagonal matrix

Keywords

matrix, diagonal, scale
