DFT and FFT C source code wanted

Post by Luis Gustavo P. M. Martin » Wed, 06 Nov 1996 04:00:00



Does anyone has the following C (or C++, Pascal) source code routines?

* Discrete Fourier Transform (DFT)
* Fast Fourier Transform (FFT)
* Sine/Cosine Discrete Transform
* Hartley Transform
* Hadamard Transform
* Walsh Transform
* Haar Transform

Please reply to my email.

You need Joerg Arndt's excellent web page :

http://www.tu-chemnitz.de/~arndt/joerg.html

Hope this helps - he certainly has the first 3.

John.
