DMDAMultiplyByJacobian1WithAD

Applies a Jacobian function supplied by ADIFOR or ADIC to a vector on each processor that shares a DMDA.

#include "petscdmda.h"   
PetscErrorCode  DMDAMultiplyByJacobian1WithAD(DM da,Vec u,Vec v,Vec f,void *w)

	da	- the DM that defines the grid
	vu	- Jacobian is computed at this point (ghosted)
	v	- product is done on this vector (ghosted)
	fu	- output vector = J(vu)*v (not ghosted)
	w	- any user data

This routine does NOT do ghost updates on vu and v upon entry.

Automatically calls DMDAMultiplyByJacobian1WithAdifor() or DMDAMultiplyByJacobian1WithAdic() depending on whether DMDASetLocalAdicMFFunction() or DMDASetLocalAdiforMFFunction() was called.
