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.
