SNESDAComputeJacobianWithAdic

 This is a universal Jacobian evaluation routine that may be used with SNESSetJacobian() as long as the user context has a DA as its first record and DASetLocalAdicFunction() has been called.

Synopsis

#include "petscda.h"     
#include "petscmg.h"    
int SNESDAComputeJacobianWithAdic(SNES snes,Vec X,Mat *J,Mat *B,MatStructure *flag,void *ptr)
Collective on SNES

Input Parameters

snes - the SNES context
X - input vector
J - Jacobian
B - Jacobian used in preconditioner (usally same as J)
flag - indicates if the matrix changed its structure
ptr - optional user-defined context, as set by SNESSetFunction()
