Dear Luca,

Which Octave version are you running?  In versions < 4.4.0 the pager is
active by default. This means, that the output of the computation is
deferred until it's done.  To avoid this, you should start your computation
with

    more off

And you might see the iteration progress when it happens.

HTH,
Kai
