#include "petscksp.h" PetscErrorCode PETSCKSP_DLLEXPORT KSPGetDiagonalScaleFix(KSP ksp,PetscTruth *fix)Collective on KSP
If PETSC_TRUE will slow things down, because it rescales the matrix before and after each linear solve. This is intended mainly for testing to allow one to easily get back the original system to make sure the solution computed is accurate enough.
This routine is only used if the matrix and preconditioner matrix are the same thing.
