VecRestoreArray2dRead
Restores a vector after VecGetArray2dRead() has been called.
Synopsis
#include "petscvec.h"
PetscErrorCode VecRestoreArray2dRead(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.
