DMCoarsenHookRemove

remove a callback set with DMCoarsenHookAdd()

Synopsis

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMCoarsenHookRemove(DM fine, PetscErrorCode (*coarsenhook)(DM fine, DM coarse, PetscCtx ctx), PetscErrorCode (*restricthook)(DM fine, Mat rstrict, Vec rscale, Mat inject, DM coarse, PetscCtx ctx), PetscCtx ctx)

Logically Collective; No Fortran Support

Input Parameters

• fine - DM on which to run a hook when restricting to a coarser level

• coarsenhook - function to run when setting up a coarser level

• restricthook - function to run to update data on coarser levels

• ctx - [optional] application context for provide data for the hooks (may be NULL)

Calling sequence of coarsenhook

• fine - fine level DM

• coarse - coarse level DM to restrict problem to

• ctx - optional application function context

Calling sequence of restricthook

• fine - fine level DM

• rstrict - matrix restricting a fine-level solution to the coarse grid, usually the transpose of the interpolation

• rscale - scaling vector for restriction

• inject - matrix restricting by injection

• coarse - coarse level DM to update

• ctx - optional application function context

Notes

This function does nothing if the coarsenhook is not in the list.

See DMCoarsenHookAdd() for the calling sequence of coarsenhook and restricthook
