VecStrideSet#
Sets a subvector of a vector defined by a starting point and a stride with a given value
Synopsis#
#include "petscvec.h"
PetscErrorCode VecStrideSet(Vec v, PetscInt start, PetscScalar s)
Logically Collective
Input Parameters#
v - the vector
start - starting point of the subvector (defined by a stride)
s - value to set for each entry in that subvector
Notes#
One must call VecSetBlockSize() before this routine to set the stride
information, or use a vector created from a multicomponent DMDA.
This will only work if the desire subvector is a stride subvector
