The only way right now is to make a plugin.  You can do it either in C
(see plugins/fn-* in the source code) or in python (see plugins/py-func).
You might be able to do it in Perl too.

Part of the numerical code in Gnumeric started out life as Fortran.  For some
type of problems, old Fortran code is the best available.  (That, unfortunately,
does not imply that it is particularly good.)
