# VecStrideSet
Sets a subvector of a vector defined by a starting point and a stride with a given value 
## Synopsis
```
#include "petscvec.h" 
PetscErrorCode VecStrideSet(Vec v, PetscInt start, PetscScalar s)
```
Logically Collective


## Input Parameters

- ***v -*** the vector
- ***start -*** starting point of the subvector (defined by a stride)
- ***s -*** value to set for each entry in that subvector



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

This will only work if the desire subvector is a stride subvector
