VecRestoreArray2dWrite#

Restores a vector after VecGetArray2dWrite() has been called.

Synopsis#

#include "petscvec.h"   
PetscErrorCode VecRestoreArray2dWrite(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.
