# VecScatterEnd
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

- ***sf -*** 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
