# VecRestoreArrays

Restores a group of vectors after `VecGetArrays()` has been called.

## Synopsis

    #include "petscvec.h"
    PetscErrorCode VecRestoreArrays(const Vec x[], PetscInt n, PetscScalar **a[])

Logically Collective; No Fortran Support

## Input Parameters

- x - the vector

- n - the number of vectors

- a - location of pointer to arrays obtained from `VecGetArrays()`

## 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 arrays obtained with `VecGetArrays()`.
