Hi - mea culpa - as pointed out by a colleague (and documented in the help
document for "hanning" in Matlab), this function produces the same window,
but without the first and last zero-weighted samples.

The only mystery that remains (I think) is - what is Matlab's "hanning"
supposed to be doing? Are there two different windows: hann and hanning (not
"hamming" - I know that's a different one)?

This is not only due to the fact that the DC component is very small,
because even if I add a DC component to the time-series, there is still
discrepancy of a factor of ~2 for that element. Does anyone have any idea
why this would be the case?

Hi -
following up on this patch, as suggested, I have added a use-case of
mlab.cohere_pairs to examples/pylab_examples/mri_with_eeg.py.

So - as Fernando mentioned above, it is looking for something that
doesn't exist anymore. With the patch (diff attached), this error no
longer occurs.

Hi - scratch that. Only *seems* to be working. Actually it hangs when I run
scripts that open figures. I am going to undo all this and forget I ever
started down this path.

Hi,
here is a suggested patch for mlab's cohere_pairs function. The old version
was broken, due to some outdated code.
Cheers,
