Re: windowed fourier transformation

[Ansley Manke <ansley@xxxxxxxxxxxxx>]

Hello Ulf,
There is an item in the Ferret mail archives with a script to do
running power spectra that calls the FFTA function.  See if
this gives you the ideas you need.

Hi ferreters,

has anybody ever done a windowed fourier analysis with
ferret?
I think it might be possible (but costly) to use ferret's
ffta and fftp external functions.
In this case has anybody written a journal file for it?

Thanks, Ulf.
