Examples for DFT

Mar 27, 2012 at 9:06 AM

I am trying to use to create a power spectrum from a simple signal of 12000 doubles.

I find the documentation of the api for FourierForward(Complex[]) a bit lacking ("Applies the forward Fast Fourier Transform (FFT) to arbitrary-length sample vectors.")

There does not seem to be any sample code for the FFT in the examples folder and the ultra short description at stops just before it gets interesting.

Do you know of any open source programs that use this api? Maybe I could use those as examples for learning.
