Maybe call it mat_from_axes?

Korijn commented 9 months ago

We could. It would be trivial (arr = np.eye(4); arr[:3, :3] = axes), but there's value in defining the convention (rows vs columns).

Any other special requirements? For example, automatic pre-normalization of the input axes, or forced orthogonality?

Your examples sound good to me!
