#include "petscao.h" PetscErrorCode AOCreateBasic(MPI_Comm comm,PetscInt napp,const PetscInt myapp[],const PetscInt mypetsc[],AO *aoout)Collective on MPI_Comm
| comm | - MPI communicator that is to share AO | |
| napp | - size of integer arrays | |
| myapp | - integer array that defines an ordering | |
| mypetsc | - integer array that defines another ordering (may be NULL to indicate the natural ordering, that is 0,1,2,3,...) |
Notes: the arrays myapp and mypetsc must contain the all the integers 0 to napp-1 with no duplicates; that is there cannot be any "holes" in the indices. Use AOCreateMapping() or AOCreateMappingIS() if you wish to have "holes" in the indices.
