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