Gerald Goertzel developed a very quick way to carry out a discrete Fourier transformation. But there seem to be very few descriptions that really explain its derivation in full.

Computers are very straight... They always do exactly what we tell them to do... Only, much too often what we tell them to do is not really what we want them to do Smile | :)

Writing Software is one of the most creative tings one can do. I have been doing this for more than ten years now and still having a lot of fun with it. Besides doing software for HMI's on C# for business, I enjoy very much to implement interesting algorithms and analyse the mathematics they are based on in my leisure time Smile | :)
