# 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 Parameters
- ***da -*** the distributed array
- ***vec -*** a vector the same size as one obtained with `DMCreateGlobalVector()` or `DMCreateLocalVector()`
## 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]!
The accessible indices are `array[zs:zs+zm-1][ys:ys+ym-1][xs:xs+xm-1]` where the values are obtained from
`DMDAGetCorners()` for a global vector or `DMDAGetGhostCorners()` for a local vector.
## Fortran Note
Use `DMDAVecGetArrayReadF90()` and pass for the array type PetscScalar,pointer :: array(:,...,:) of the appropriate
dimension. For a `DMDA` created with a dof of 1 use the dimension of the `DMDA`, for a `DMDA` created with a dof greater than 1 use one more than the
dimension of the `DMDA`.
The order of the indices is `array(xs:xs+xm-1,ys:ys+ym-1,zs:zs+zm-1)` (when dof is 1) otherwise
`array(0:dof-1,xs:xs+xm-1,ys:ys+ym-1,zs:zs+zm-1)` where the values are obtained from
`DMDAGetCorners()` for a global vector or `DMDAGetGhostCorners()` for a local vector.
