Elisp math library that handles matrices made up by lists

[Bruno Félix Rezende Ribeiro]

Does anyone have any knowledge about a elisp math library to handle and operate 
on
matrices built as lists of (equal length) lists, like this:

((1 2 3)
 (4 5 6)
 (7 8 9))

To transpose, to extract columns, to calculate sum, product, determinant
and other correlate operations?

If there is none, would one be reasonably relevant to elisp programmers
in general to worth the implementation?  Or do you think it's better to
duplicate and adapt the needed functions, probably only a small subset
of that library, to every project that one want to distribute to Emacs
users?

Thanks in advance.
