The book consists of eight chapters. Fast Fourier Transform Supplemental reading in CLRS: Chapter 30 The algorithm in this lecture, known since the time of Gauss but popularized mainly by Cooley and Tukey in the 1960s, is an example of the divide-and-conquer paradigm. By contrast, this book aims at efficient discovery in time series, rather than prediction, and its novelty lies in its algorithmic contributions and its simple, practical algorithms and case studies. Following an introduction to the basis of the fast Fourier transform (FFT), this book focuses on the implementation details on FFT for parallel computers.
