DMDAVecGetArrayDOF

Returns a multiple dimension array that shares data with the underlying vector and is indexed using the global dimensions.

#include "petscdmda.h"   
PetscErrorCode  DMDAVecGetArrayDOF(DM da,Vec vec,void *array)

Not Collective

	da	- the distributed array
	vec	- the vector, either a vector the same size as one obtained with DMCreateGlobalVector() or DMCreateLocalVector()

array -the array

Call DMDAVecRestoreArrayDOF() once you have finished accessing the vector entries.

In C, the indexing is "backwards" from what expects: array[k][j][i][DOF] NOT array[i][j][k][DOF]!
