# DMDAVecGetArrayDOF
Returns a multiple dimension array that shares data with the underlying vector and is indexed using the global dimensions. 
## Synopsis
```
#include "petscdmda.h"   
PetscErrorCode DMDAVecGetArrayDOF(DM da, Vec vec, void *array)
```
Logically collective


## Input Parameters

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



## Output Parameter

- ***array -*** the array





## Notes
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]!

In Fortran 90 you do not need a version of `DMDAVecRestoreArrayDOF()` just use `DMDAVecRestoreArrayF90()` and declare your array with one higher dimension,
see src/dm/tutorials/ex11f90.F
