This book offers a unified presentation of Fourier theory and corresponding algorithms emerging from new developments in function approximation using Fourier me

This unified, self-contained book examines the mathematical tools used for decomposing and analyzing functions, specifically, the application of the [discrete]

This book provides useful reference material for those concerned with the use of Fourier analysis and computational fluid dynamics.

"The DFT can be understood as a numerical approximation to the Fourier transform. However, the DFT has its own exact Fourier theory, and that is the focus of th
