If you use the numpy.matrix type instead of numpy.array, the * operator becomes matrix multiplicaton.

hmmm, I thought the matrix class was deprecated? At least it says so in the official numpy documentation:

https://numpy.org/doc/stable/reference/generated/numpy.matri...

Anyhow, the * operator does not work with sparse matrices, and you really don't want to maintain two versions of your formulas. Thus, you are unfortunately stuck with @ or .dot

I guess there might be a much more math-friendly library than numpy, but I have never found it.

Huh, you're right. Bummer, I hadn't noticed that yet. I agree that an ergonomic matrix class is sorely missing in the Python ecosystem. It shouldn't even be that hard to implement, since all the plumbing is already there.
