# VecStrideScaleAll
Scales the subvectors of a vector defined by a starting point and a stride. 
## Synopsis
```
#include "petscvec.h" 
PetscErrorCode VecStrideScaleAll(Vec v, const PetscScalar *scales)
```
Logically Collective on Vec


## Input Parameters

- ***v -*** the vector
- ***scales -*** values to multiply each subvector entry by



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

The dimension of scales must be the same as the vector block size
