Looks good. I'm a big fan of narray to get decent performance for array operations, interesting to see how the rewrite of that will perform. Narray is pretty damn close to realtime compared to native ruby implementations.

realtime what? Realtime like C? Realtime like ATLAS or MKL?

realtime like it's fast fortran matrix stuff. compared to slow-as-molasses ruby native Array#mean (which has to be implemented in ruby).
