your example works perfectly well on my PC running GNU/Debian
3.0r1 as you wrote it, i.e. without scaling f1 as Etienne
suggested. Thus, I would say this is not a problem of Octave
itself, but probably a problem of the particular version you're
running.

Which OS, platform and Octave version are you using? Did you
compile it yourself? If not, where did you get it from?
