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 on Vec
Input Parameter
| 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
