Hello

I can successfully execute


#+BEGIN_SRC matlab
A=[3 4; 5 6]
b=[5;6]
A\b
#+END_SRC

#+RESULTS:
|  -3 |
| 3.5 |

However 
#+BEGIN_SRC matlab
syms a b
A=[a,b;b,a]
eig(A) 
#+END_SRC


Does not work

I obtain

executing Matlab code block...
Wrote /tmp/babel-2948rpV/ob-input-2948ACJ
Error reading results: (beginning-of-buffer)
Code block produced no output.


However the code can be executed in matlab giving


ans =
 
 a + b
 a - b


Any comments?

Thanks

Uwe Brauer
