Help in producing a Matlab code that simulates Sine and cosine from rotating vector in a circle

There are interesting animations for education purposes to teach the relationship between imaginary numbers and trigonometry. An example is the animation found in:

Does anyone have (or can suggest) a Matlab code that produces the above animation?

Many thanks

It probably wouldn't be too hard to do something like that using the techniques described in this section of the documentation.
