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 VecGetArray1dRead()

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.
