There is a Ruby wrapper for the core R math library (Rmath) on RAA. I
got it working a few weeks ago but had to drop the project in favor of
something I get paid to do (with R, however). I hate to show up on a
Ruby list as an R bigot, but, well, I am. :)

Specifically for neuroimaging, one would need a Ruby wrapper for the
BLAS and LAPACK libraries and probably wfft. I don't think either is
particularly difficult to do, given the excellent instructions on the
Ruby/C interface in the Pickaxe book. I just personally have little
motivation to do it.

By the way, if you're going to use BLAS and LAPACK, go the extra mile
and use the Automatically Tuned Linear Algebra Subroutines (ATLAS) as
well. You'll get near machine speed on decent-sized problems.
