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#

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.
