toolbox fft

Hello,

Is there a matlab toolbox with a gui that makes it easy to do FFT or other frequency analysis of sampled data?

Yes, the Signal Processing Toolbox has sptool. You can launch the spectrum viewer from there and perform both nonparametric and parametric (AR) spectral analysis.

Enter:

>>sptool

Then File -> Import to import your data, then you can perform spectral analysis under "spectra" by entering "Create" with your signal selected.
