KSPSetPC#

Sets the preconditioner to be used to calculate the application of the preconditioner on a vector into a KSP.

Synopsis#

#include "petscksp.h" 
#include "petscmat.h" 
PetscErrorCode KSPSetPC(KSP ksp, PC pc)

Collective

Input Parameters#

  • ksp - the KSP iterative solver obtained from KSPCreate()

  • pc - the preconditioner object (if NULL it returns the PC currently held by the KSP)

Note#

This routine is almost never used since KSP creates its own PC when needed. Use KSPGetPC() to retrieve the preconditioner context instead of creating a new one.
