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

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
