I coded portfolio optimization code and did a lot of prototyping
in octave (free Matlab look-alike) and ruby, then after some profiling 
wrote a few functions in C and kept the rest in ruby and was happy. SWIG
is good for easily getting your C-code playing nicely along with ruby.

At the beginning as I had tons of existing octave code, I simply set up
a pipe with octave to farm out some computation.

Additionaly you might want to look at the ruby-bindings of the gsl-library.

Good luck,
