DMDAVecGetArrayDOFRead
Returns a multiple dimension array that shares data with the underlying vector and is indexed using the global dimensions.
Synopsis
#include "petscdmda.h"
PetscErrorCode DMDAVecGetArrayDOFRead(DM da,Vec vec,void *array)
Not Collective
Input Parameter
Output Parameter
array -the array
Notes
Call DMDAVecRestoreArrayDOFRead() 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]!
In Fortran 90 you do not need a version of DMDAVecRestoreArrayDOF() just use DMDAVecRestoreArrayReadF90() and declare your array with one higher dimension,
