@folcon Any general book/literature that uses matrix algebra and matrices in general to model physics will be applicable. The Numerical Algebra for Programmers will get you started with both matrices/LA, and how to program in them. The only missing piece is the physics part, but, as I wrote, it's a specific application domain that should be explored from the relevant literature.

That's fair 😃... I'm more wondering how to use neanderthal in that domain, for example, is it better to create fixed size matrices to represent 2d / 3d entities? So a 100 x 2 matrix for 100 entities? Or is it possible to dynamically grow / shrink them as my entity counts change? If they have to be fixed size, how do you track which ones are "used" if you do? Perhaps just have a 2d vector for each property stored on the entity map (which does not sound fast 😃...)? Is there any resources or short tutorials that exist that I could act as a starting point? For example I've looked over the linear algebra tutorials, on dragan.rocks, but they're very much looking at single values vs say the clojure sound article which I do want to try later when I want to get sound working, which looks like I could just build something by following it. I'm currently muddling my way using quil/processing. So perhaps it's worthwhile coming back here once I have a clearer idea of the space, as I'm getting the impression neanderthal is much lower level than I was thinking. IE, I should be looking at building game engines book and building up from there, which is a rabbit hole I only want to start going down once I've gotten a clearer idea what I want to build 😃...
