GetRanking( obj)
obj
-
a LAVF object that its symmetry determinings system is in rif-reduced form.
For a LAVF object, the GetRanking method returns the ranking of the rif-reduced symmetry determining system as a list (or a list of lists) of dependent variable names, if available.
This method is front-end to the GetRanking method of a LHPDE object. That is, let S be the determining systems of LAVF objects L then GetRanking(L) equals GetRanking(S).
The returned output - ranking of a LAVF object - is consistent with the ranking that is used on the DEtools[rifsimp] command. See ranking for more detail.
This method is associated with the LAVF object. For more detail, see Overview of the LAVF object.

The GetRanking command was introduced in Maple 2020.
