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
