This message is from July, but meanwhile I upgraded to Ubuntu 16.04
matlab 2016b which includes the python engine/kernel and finally
I installed the Jupiter matlab kernel via pip, however I tried to follow
your recommendations below:

Here I obtain the following error:

Debugger entered--Lisp error: (void-function org-babel-execute:matlab)
  org-babel-execute:matlab("x = [1, 2, 3, 4, 5];\nfprintf('|%d', x)"

What is the problem? Which package do I miss, ipython is installed in 
/usr/local/bin

Thanks
