VecRestoreArray1dRead

Restores a vector after VecGetArray1dRead() has been called.

Synopsis

#include "petscvec.h"   
PetscErrorCode  VecRestoreArray1dRead(Vec x,PetscInt m,PetscInt mstart,PetscScalar *a[])
Logically Collective

Input Parameters

x - the vector
m - first dimension of two dimensional array
mstart - first index you will use in first coordinate direction (often 0)
a - location of pointer to array obtained from VecGetArray21()

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 VecGetArray1dRead().

This routine actually zeros out the a pointer.
