Hmm, shouldn't do. Could you post your example? Have you activated both
octave and matlab? What is the value of your org-babel-load-languages?

For me C-c C-c and C-c C-v e on

#+begin_src matlab
1+1
#+end_src

result in

/bin/bash: matlab: command not found

You can confirm which language is running by using the "version"
command. Here's what I get (note I have to run matlab on a remote
computer because I don't have it on my laptop).

--8<---------------cut here---------------start------------->8---
#+begin_src octave :results output
version
#+end_src

#+results:
: ans = 3.2.4

#+begin_src matlab :dir /ddavison@tombstone.princeton.edu:/ :results output
version
#+end_src

#+results:
#+begin_example

The default version of Matlab in /usr/licensed/bin is matlab-R2009b

The following versions are available in /usr/licensed/bin:
     matlab-R2009b
   matlab-R2009a
   matlab-R2008b

In general we would appreciate any notes on problems encountered when
running Org-babel on Windows.
