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
