It sometimes does and it sometimes doesn't work under Windows 2000 and
Octave 2.9.13, with the same error message though. But if it (kind of)
works it yields different results each time: different power in the
upper left and lower right corners (either orange or pink), and the
sweep sometimes stops on its way upwards and starts at the x axis again.
The axes are not labelled properly. They seem to reflect the number of
entries in x and y respectively instead of frequencies and time. And
with regard to compatability: An old Matlab version (R11.2), when
specgram was still called specgram and not spectrogram as it is today,
the axes would be labelled 'Time' and 'Frequency'.
