KSPGetDiagonalScale#
Checks if KSP
solver scales the matrix and right hand side
Synopsis#
#include "petscksp.h"
#include "petscmat.h"
PetscErrorCode KSPGetDiagonalScale(KSP ksp, PetscBool *scale)
Not Collective
Input Parameter#
ksp - the
KSP
context
Output Parameter#
scale -
PETSC_TRUE
orPETSC_FALSE
Notes#
BE CAREFUL with this routine: it actually scales the matrix and right
hand side that define the system. After the system is solved the matrix
and right hand side remain scaled unless you use KSPSetDiagonalScaleFix()
