At run time, your program could write out a file containing a

standalone C function which implements the mathematical function,

compile this to a shared library (or DLL), dynamically link it in, and

call the function as required.

GNU Libtool (http://www.gnu.org/software/libtool/libtool.html)

will do this portably on Unix-like systems and on windows using Cygwin.
