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

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.
