VecSetBlockSize#

Sets the block size for future calls to VecSetValuesBlocked() and VecSetValuesBlockedLocal().

Synopsis#

#include "petscvec.h"   
PetscErrorCode VecSetBlockSize(Vec v, PetscInt bs)

Logically Collective

Input Parameters#

v - the vector
bs - the blocksize

Note#

All vectors obtained by VecDuplicate() inherit the same blocksize.

Vectors obtained with DMCreateGlobalVector() and DMCreateLocalVector() generally already have a blocksize set based on the state of the DM
