Hi John, thank you very much for your kind words! Yes, I remember JuliaCon 2017 and now I’m super nostalgic of real-life-meetings :') Soon I believe we’ll meet in person again! haha!
Interesting! I’ve given pretty much identical exercises but asked for a different approach of first calculating the orbits and then using linear interpolation to obtain the crossings of the hyperplane. If you want I can share with you the exercises/solutions. The NLSolve way is something I haven’t done so far (I’m actually using Roots.jl and DiffEq’s interpolation capabilities to find PSOS in DynamicalSystems.jl), so if you have any code snippet lying around I’d be glad to have a look!
Awww thanks, but don’t rush coz you’ll be getting one in your mailbox soon (Springer will give us a batch to distribute as we please)!
hehe, it’s a small world, isn’t it? I think delay embeddings is one of the things one really, really has to stress a lot in an NLD course. Apparently many people approach delay embeddings as this “off the shelf magic tool that can be applied anywhere”, and this isn’t a productive way forwards… So on purpose one of the exercise datasets on delay embeddings is just crap, to train the students prepare for the real world hahaha
