String processing in MATLAB (Octave, really) is agony, so I tend to use 
a hybrid of Perl and Octave.  I've tried Ruby plus NArray/rb-gsl and 
Perl plus PDL, but neither has Octave's huge number of linear algebra 
functions (SVD, least-squares, eigenvalues, ...) or plotting support. 
Compact arrays are crucial, but they're only a small part of the story.
