VecScatterEnd

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

Synopsis

#include "petscvec.h"    
PetscErrorCode  VecScatterEnd(VecScatter ctx,Vec x,Vec y,InsertMode addv,ScatterMode mode)
Neighbor-wise Collective on VecScatter

Input Parameters

ctx - scatter context generated by VecScatterCreate()
x - the vector from which we scatter
y - the vector to which we scatter
addv - one of ADD_VALUES, MAX_VALUES, MIN_VALUES or INSERT_VALUES
mode - the scattering mode, usually SCATTER_FORWARD. The available modes are: SCATTER_FORWARD, SCATTER_REVERSE

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
