That's good. I think there are too many "How should I call this module?" 
questions here (and elsewhere). See for example:

name-a-flickr-module

I don't have any other comments except for thanking you for:

1. Thanking you for releasing this useful code.

2. Asking if your module can work with other mathematical APIs on CPAN such as 
http://search.cpan.org/dist/PDL/ , http://search.cpan.org/dist/Math-GSL/ ,  
http://search.cpan.org/search?query=vector&mode=all , etc.
