Sinopsis

This book offers a unified presentation of Fourier theory and corresponding algorithms emerging from new developments in function approximation using Fourier methods.It starts with a detailed discussion of classical Fourier theory to enable readers to grasp the construction and analysis of advanced fast Fourier algorithms introduced in the second part, such asá nonequispacedá and sparse FFTs in higher dimensions.Lastly, it contains a selection of numerical applications, including recent research results on nonlinear function approximation by exponential sums.The code of most of the presented algorithms is available in the authorsâÇÖ public domain software packages.Students and researchers alike benefit from this unified presentation of Fourier theory and corresponding algorithms.
