I was also going to suggest that if someone did this, they might want to
try to address octave at the same time. 

Darlan -- would you like to share your initial version of octave
support? If we get it onto a git repository then we can all have a look
and maybe make a bit of progress. Either post it, or contact me off-line
for the admin details for http://repo.or.cz/w/org-mode/babel.git.

I don't use either language but here are some comments about the various
tasks and guesses about how hard they would be.

If someone could comment on the extent to which differences between
matlab and octave (running as command-line external processes) are going
to make shared org-babel support problematic that would probably be
useful.

- external process :results output
  Running octave as an external process under linux/OS X and collecting
  stdout shouldn't be too hard. Presumably same for matlab? Windows
  support: unavailable for matlab, but probably feasible for octave.

- external process :results value
  This basically involves (in matlab/octave) writing vectors and arrays
  to a tabular file (and then using existing code to import the org
  table, but this bit can be taken from the files for another language)

- :session
  At first glance it looks like there's an inferior octave mode that
  should be suitable for use
  with :session. Darlan -- do you have experience with this?

  http://www.gnu.org/software/octave/doc/interpreter/Running-Octave-From-Within-Emacs.html#Running-Octave-From-Within-Emacs

- Matlab :session on Windows
  Getting org-babel to work with the MatLab "EmacsLink" module may well be
  possible, but I would only be able to help very superficially.
