If MATLAB is her preferred environment, I would suggest GNU-Octave as a 
free replacement. It lags behind in graphics, but other than that it's 
very useful, and Octave 3.0 is nearing its release and promises to close 
most of the gap.

I have a negative experience with PDL - after I wrote some program with 
it, when I upgraded PDL I suddenly found that I have no eigenvalues 
because of a bug, so my program wouldn't work at all.

The only thing I can really say about it is that if you must use Perl 
for physics work, PDL is probably better than plain Perl.

Also there's numpy for Pythoneers, scilab (not exactly MATLAB 
compatible, but close enough), and possibly others.

And on the non-free front, MATLAB is available for Linux too.
