AOCreateMapping#
Creates an application mapping using two integer arrays.
Synopsis#
#include "petscao.h" 
PetscErrorCode AOCreateMapping(MPI_Comm comm, PetscInt napp, const PetscInt myapp[], const PetscInt mypetsc[], AO *aoout)
Input Parameters#
- comm - MPI communicator that is to share the - AO
- napp - size of integer arrays 
- myapp - integer array that defines an ordering 
- mypetsc - integer array that defines another ordering (may be - NULLto indicate the identity ordering)
Output Parameter#
- aoout - the new application mapping 
Options Database Key#
- -ao_view - call - AOView()at the conclusion of- AOCreateMapping()
Note#
The arrays myapp and mypetsc need NOT contain the all the integers 0 to napp-1, that is there CAN be “holes”  in the indices.
Use AOCreateBasic() or AOCreateBasicIS() if they do not have holes for better performance.
