VecRestoreArray4d

Restores a vector after VecGetArray4d() has been called.

Synopsis

#include "petscvec.h"   
PetscErrorCode VecRestoreArray4d(Vec x, PetscInt m, PetscInt n, PetscInt p, PetscInt q, PetscInt mstart, PetscInt nstart, PetscInt pstart, PetscInt qstart, PetscScalar ****a[])

Logically Collective

Input Parameters

• x - the vector

• m - first dimension of four dimensional array

• n - second dimension of the four dimensional array

• p - third dimension of the four dimensional array

• q - fourth dimension of the four dimensional array

• mstart - first index you will use in first coordinate direction (often 0)

• nstart - first index in the second coordinate direction (often 0)

• pstart - first index in the third coordinate direction (often 0)

• qstart - first index in the fourth coordinate direction (often 0)

• a - location of pointer to array obtained from VecGetArray4d()

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.
