Right: your code uses the matlab-shell, which writes its results in the
*MATLAB* shell buffer, but I want the result (at least optional) to be
written in the org buffer. So a typical org file after executing matlab
looks like

This is what the hack does and it does it nicely, the only problem is
that every time I execute the code matlab is started again, and for more
recent versions of matlab this can take some time. So the question is
whether the hack I used, could use the matlab-shell.
