In the US, at least, one cannont copyright or patent a "bare algorithm." 
Mathematical formulae and algorithms of a purely mathematical nature are 
deemed "ideas."

This fact alone is of course not enough to prevent somone from taking you 
to court, where you'd then have to prove that your software really was 
nothing more than a mathematical algorithm expressed in code. For a 
mathematical library, it would seem a relatively easy thing to prove.

Of course, IANAL.
