One of the Mac freeware programs that I tried comes with a Lyapunov folder, but I'll be darned if I can recall which one...? (Of course, that doesn't guarantee that it will do them properly!) The apps are all on my old Mac, which will not talk to my new Mac until we buy a $$ piece of networking hardware....... So I'm unable to look it up for you (and fractalless, myself!!) until I can go out and download the apps again. Did you try a search using Lyapunov as a key word??
