What happens when you try C-c C-c or C-c C-v e ? There is an issue with
matlab and octave: they return the value of the last /unassigned/
computation, so simply ending the code block with a variable name "x" is
not enough. Could you try one of the following schemes please, and let
us know if that solves it:

#+begin_src matlab :exports results
n = [1:10];
x = 5*n+4;
ans = x
#+end_src

#+begin_src matlab :exports results
n = [1:10];
x = 5*n+4;
x + 0
#+end_src

There was a little typo in your original block: the keyword is
":exports" with an s.
