Synopsis

#include "petscdm.h"

#include "petscds.h"     
PetscErrorCode VecSetDM(Vec v, DM dm)

Not Collective

Input Parameters

• v - The Vec

• dm - The DM

Note

This is rarely used, generally one uses DMGetLocalVector() or DMGetGlobalVector() to create a vector associated with a given DM

This is NOT the same as DMCreateGlobalVector() since it does not change the view methods or perform other customization, but merely sets the DM member.
