I changed my mind. The second patch was so easy that here is the complete patch that includes allowing psd, csd, cohere_pairs, cohere, and specgram to pass in a vector of length NFFT for "window".
I'll go attach this patch to the SF site for the ticket I created yesterday.
Thanks

Hi,
I'll do these patches a little at a time.
Here is a patch to show a complex spectrogram with the negative frequencies flipped down. I've also attached a modified version of the spectrogram_demo.py that creates the two signals as complex exponentials so they are only in one half of the spectrum (long signal positive, short signal negative).
Basically, if the input signal is complex then the whole spectrogram is shown. If the input is real then just the positive frequencies are shown.
Next I'll work on the following as discussed.
Thanks

This is fine -- I suggest using the matplotlib.cookbook.iterable
function or the python builtin callable function to do the check.
Whatever changes you make for specgram should also be ported into psd,
csd and cohere.
