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
