VecSetSizes#
Sets the local and global sizes, and checks to determine compatibility of the sizes
Synopsis#
#include "petscvec.h"
PetscErrorCode VecSetSizes(Vec v, PetscInt n, PetscInt N)
Collective
Input Parameters#
v - the vector
n - the local size (or
PETSC_DECIDEto have it set)N - the global size (or
PETSC_DETERMINEto have it set)
Notes#
N cannot be PETSC_DETERMINE if n is PETSC_DECIDE
If one processor calls this with N of PETSC_DETERMINE then all processors must, otherwise the program will hang.
