Mathematica function CForm[] will generate C code, but there are restrictions.  
Specifically, CForm will not expand built-in functions like FindRoot.  But I 
have used CForm to generate the blob of code needed to perform vector and matrix 
computations in embedded processors too small and too odd for Mathematica
to run on, and/or where Mathematica is itself far too slow.

The real reason to use CForm here was to cut down on coding errors in a messy 
bit of coordinate-transform code.
