      7:    DMDAVecGetArray - Returns a multiple dimension array that shares data with
      8:       the underlying vector and is indexed using the global dimensions.

     10:    Logically collective on Vec

     12:    Input Parameter:
     13: +  da - the distributed array
     14: -  vec - the vector, either a vector the same size as one obtained with DMCreateGlobalVector() or DMCreateLocalVector()

     16:    Output Parameter:
     17: .  array - the array

     19:    Notes:
     20:     Call DMDAVecRestoreArray() once you have finished accessing the vector entries.

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

     24:     If vec is a local vector (obtained with DMCreateLocalVector() etc) then the ghost point locations are accessible. If it is
     25:     a global vector then the ghost points are not accessible. Of course with the local vector you will have had to do the

     27:     appropriate DMGlobalToLocalBegin() and DMGlobalToLocalEnd() to have correct values in the ghost locations.

     29:   Fortran Notes: From Fortran use DMDAVecGetArrayF90() and pass for the array type PetscScalar,pointer :: array(:,...,:) of the appropriate
     30:        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
     31:        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
     32:        array(0:dof-1,xs:xs+xm-1,ys:ys+ym-1,zs:zs+zm-1) where the values are obtained from
     33:        DMDAGetCorners() for a global array or DMDAGetGhostCorners() for a local array. Include petsc/finclude/petscdmda.h90 to access this routine.

     35:   Due to bugs in the compiler DMDAVecGetArrayF90() does not work with gfortran versions before 4.5

    405:    Notes:
    406:     Call DMDAVecRestoreArrayDOFRead() once you have finished accessing the vector entries.

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

    410:     In Fortran 90 you do not need a version of DMDAVecRestoreArrayDOF() just use  DMDAVecRestoreArrayReadF90() and declare your array with one higher dimension,
