How can I know more details about the function spap2?

The built-in function spap2 returns the B-form of the spline. My main goal is to know how exactly it calculates the coefficients it returns for each term in the B form, meaning the coefficients of each of the B's in the B form.

Why don't you just try:
edit spap2
From there you should be able to read for yourself. As far as I can see most functions are plain .m-files.

What are you planning to do with that information? Are you planning to cite the function in a paper, for example?
The Algorithm section on the spap2 documentation page describes generally the approach it takes.
