And I was just trying to help. :) Easy to miss that link. Unfortunately Wikipedia generally isn't great for motivation on math topics.
Tensor ops in e.g. pytorch are pretty opaque to me, too much implicit on shapes which can change as you go down a pipeline. Maybe I'll come to appreciate it better.
And thank you. (I come from an old generation of people trained in linear algebra and differential geometry, well before the current ML era so I am holding onto my "get off my lawn" grumpiness.)
