Re: problem with ob-octave (matlab)

[Eric S Fraga <e.fraga@ucl.ac.uk>]

I don't have MATLAB on the system I'm on at the moment but trying your
(slightly modified) example with octave instead works:

#+begin_src org
  ,#+BEGIN_SRC octave :results output
    pkg load symbolic
    syms a b
    A=[a,b;b,a]
    eig(A) 
  ,#+END_SRC

  ,#+results:
  ,#+begin_example
  OctSymPy v2.2.4: this is free software without warranty, see source.
  Initializing communication with SymPy using a popen2() pipe.
  Some output from the Python subprocess (pid 28058) might appear next.

  OctSymPy: Communication established.  SymPy v0.7.6.1.
  A = (sym 2×2 matrix)

    ⎡a  b⎤
    ⎢    ⎥
    ⎣b  a⎦

  ans = (sym 2×1 matrix)

    ⎡       ____⎤
    ⎢      ╱  2 ⎥
    ⎢a - ╲╱  b  ⎥
    ⎢           ⎥
    ⎢       ____⎥
    ⎢      ╱  2 ⎥
    ⎣a + ╲╱  b  ⎦


  ,#+end_example

#+end_src 

I don't know if this helps you at all and/or whether the issue is with
MATLAB...
