ISCreate
Creates an index set object.
Synopsis
#include "petscis.h"
PetscErrorCode ISCreate(MPI_Comm comm,IS *is)
Collective on MPI_Comm
Input Parameters
comm -the MPI communicator
Output Parameter
is -the new index set
Notes
When the communicator is not MPI_COMM_SELF, the operations on IS are NOT
conceptually the same as MPI_Group operations. The IS are then
distributed sets of indices and thus certain operations on them are
collective.
