VecStrideSet

Sets a subvector of a vector defined by a starting point and a stride with a given value

#include "petscvec.h" 
PetscErrorCode  VecStrideSet(Vec v,PetscInt start,PetscScalar s)

Logically Collective on Vec

	v	- the vector
	start	- starting point of the subvector (defined by a stride)
	s	- value to set for each entry in that subvector

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
