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
