Cool.  It might as simple as addpathing to the m-code and running your Matlab
code in Octave, though you are pretty much confined to the command line.

You might want to look at the "%!test" functionality in Octave, btw.

I don't know what anybody would write about -- if an EEM matrix is stored as a
regular 2-D matrix, Octave would neither add nor subtract anything from an
algorithm implemented in Matlab, except for license fees and encumbrances. It
should be completely transparent, and if it isn't, submit it as a bug.  (I wish
that sort of thing was worhty of a journal article....)
