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
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
Notes#
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
