AOApplicationToPetsc

 Maps a set of integers in the application-defined ordering to the PETSc ordering.

Synopsis

#include "petscao.h" 
PetscErrorCode  AOApplicationToPetsc(AO ao,PetscInt n,PetscInt ia[])
Collective on AO

Input Parameters

ao - the application ordering context
n - the number of integers
ia - the integers; these are replaced with their mapped value

Output Parameter

ia -the mapped integers

Note

Any integers in ia[] that are negative are left unchanged. This allows one to convert, for example, neighbor lists that use negative entries to indicate nonexistent neighbors due to boundary conditions, etc.

Integers that are out of range are mapped to -1
