PCShellSetPostSolve#
Sets routine to apply to the operators/vectors after a KSPSolve() is applied. This usually does something like scale the linear system in some application specific way.
Synopsis#
#include "petscpc.h"
PetscErrorCode PCShellSetPostSolve(PC pc, PetscErrorCode (*postsolve)(PC pc, KSP ksp, Vec xin, Vec xout))
Logically Collective
Input Parameters#
pc - the preconditioner context
postsolve - the application-provided presolve routine
Calling sequence of postsolve#
pc - the preconditioner
ksp - the
KSPthat containspcxin - input vector
xout - output vector
Note#
You can get the PCSHELL context set with PCShellSetContext() using PCShellGetContext() if needed by postsolve.
