PCShellSetApply#
Sets routine to use as preconditioner.
Synopsis#
#include "petscpc.h"
PetscErrorCode PCShellSetApply(PC pc, PetscErrorCode (*apply)(PC pc, Vec xin, Vec xout))
Logically Collective
Input Parameters#
pc - the preconditioner context
apply - the application-provided preconditioning routine
Calling sequence of apply#
pc - the preconditioner, get the application context with
PCShellGetContext()xin - input vector
xout - output vector
Note#
You can get the PCSHELL context set with PCShellSetContext() using PCShellGetContext() if needed by apply.
