# 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 Parameter

| 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
