The document describes some fast transform algorithms for signal processing, with a precise description of all the routines developed, focusing on calling interfaces. The discrete theory point of view is taken, letting the reader refer to the continuous theory for a wider vision of the subject. All these algorithms are based on Cooley-Tukey flow graphs, and have been coded in C. These routines have been put in a library (libTR.a) for easier use. Some useful tools are described and then the coding of Fourier, Walsh, Paley, Hadamard and Haar transforms.
