VecRestoreArray1dWrite
Restores a vector after VecGetArray1dWrite() has been called.
Synopsis
#include "petscvec.h"
PetscErrorCode VecRestoreArray1dWrite(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 VecGetArray1d().
This routine actually zeros out the a pointer.
Concepts: vector^accessing local values as 1d array
