Ends a generalized scatter from one vector to another. Call after first calling VecScatterBegin().

Synopsis#

#include "petscsf.h" 
PetscErrorCode VecScatterEnd(VecScatter sf, Vec x, Vec y, InsertMode addv, ScatterMode mode)

Neighbor-wise Collective

Input Parameters#

Notes#

If you use SCATTER_REVERSE the arguments x and y should be reversed, from the SCATTER_FORWARD.

y[iy[i]] = x[ix[i]], for i=0,…,ni-1
