Matlab introduced a function angvel since 2020. According to the documentation, the function is supposed to compute angular velocity tensor from a sequence of quaternions.
The details seem puzzling. No units are mentioned in the documentation; explicit passing of timestep dt is required; check-runs on elementary rotations produce mixed results.

I wrote a program that creates an ellipse made of a series of points that can be rotated by an angle, psi, in the xy plane. I am using a rotation matrix to rotate the ellipse.
