# VecStrideScatterAll
Scatters all the single components from separate vectors into a multi-component vector. 
## Synopsis
```
#include "petscvec.h" 
PetscErrorCode VecStrideScatterAll(Vec s[], Vec v, InsertMode addv)
```
Collective


## Input Parameters

- ***s -*** the location where the subvectors are stored
- ***addv -*** one of `ADD_VALUES`, `INSERT_VALUES`, `MAX_VALUES`



## Output Parameter

- ***v -*** the multicomponent vector





## Notes
One must call `VecSetBlockSize()` before this routine to set the stride
information, or use a vector created from a multicomponent `DMDA`.

The parallel layout of the vector and the subvector must be the same;
i.e., nlocal of v = stride*(nlocal of s)

Not optimized; could be easily
