set a local Jacobian evaluation function

Synopsis

#include "petscdmda.h" 
#include "petscsnes.h" 
PetscErrorCode DMDASNESSetJacobianLocal(DM dm,PetscErrorCode (*func)(DMDALocalInfo*,void*,Mat,Mat,void*),void *ctx)
Logically Collective

Input Arguments

dm - DM to associate callback with
func - local Jacobian evaluation
ctx - optional context for local Jacobian evaluation

Calling sequence

For PetscErrorCode (*func)(DMDALocalInfo *info,void *x,Mat J,Mat M,void *ctx),
info - DMDALocalInfo defining the subdomain to evaluate the Jacobian at
x - dimensional pointer to state at which to evaluate Jacobian (e.g. PetscScalar *x or **x or ***x)
J - Mat object for the Jacobian
M - Mat object for the Jacobian preconditioner matrix
ctx - optional context passed above
