PetscErrorCode DMPlexCompareOrientations(DM dm, PetscInt p, PetscInt masterConeSize, const PetscInt masterCone[], PetscInt *start, PetscBool *reverse)
Not Collective
Input Parameters
| dm | - The DM (DMPLEX)
|
| p | - The DAG point whose cone is compared
|
| masterConeSize | - Number of the reference cone points passed (at least 2 and at most size of the cone of p)
|
| masterCone | - The reference cone points
|
Output Parameters
| start | - The new starting point within the cone of p to make it conforming with the reference cone
|
| reverse | - The flag whether the order of the cone points should be reversed
