Examples for DFT

Mar 27, 2012 at 10:06 AM

I am trying to use Math.net 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 numerics.mathdotnet.com/integral-transforms 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.
