# VecRestoreArray2d

Restores a vector after VecGetArray2d() has been called.

### Synopsis

    #include "petscvec.h"
    PetscErrorCode  VecRestoreArray2d(Vec x,PetscInt m,PetscInt n,PetscInt mstart,PetscInt nstart,PetscScalar **a[])

Logically Collective

### Input Parameters

| x | - the vector
| m | - first dimension of two dimensional array
| n | - second dimension of the two dimensional array
| mstart | - first index you will use in first coordinate direction (often 0)
| nstart | - first index in the second coordinate direction (often 0)
| a | - location of pointer to array obtained from VecGetArray2d()

### Notes

For regular PETSc vectors this routine does not involve any copies. For any special vectors that do not store local vector data in a contiguous array, this routine will copy the data back into the underlying vector data structure from the array obtained with VecGetArray().

This routine actually zeros out the a pointer.
