Hi Enric,
yes, it is the intended behavior.

Now the demo system should be able to execute MATLAB code by default  
and therefore it complains if in the configuration file it doesn't  
find the MATLAB paths.

It's a design decision but we can avoid showing this warning if we  
think it's better.

Of course, it'll work as usual even if you don't have MATLAB installed.
In any case, use can simple comment the line in your local  
installation if you prefer not to see the warning (in empty_app.py).

Best,
Miguel
