#include "petscao.h" PetscErrorCode AOCreateMappingIS(IS isapp, IS ispetsc, AO *aoout)
|comm||- MPI communicator that is to share AO|
|isapp||- index set that defines an ordering|
|ispetsc||- index set that defines another ordering, maybe NULL for identity IS|
Notes: the index sets isapp and ispetsc need NOT contain the all the integers 0 to N-1, that is there CAN be "holes" in the indices. Use AOCreateBasic() or AOCreateBasicIS() if they do not have holes for better performance.
