Discrete Fourier Transforms,ation of Fourier coefficients, Fourier transforms, or trigonometric interpolation, lead to the DFT. We also present barycentric formulas for interpolating trigonometric polynomials. In Sect. 3.2, we study the basic properties of the Fourier matrix and of the DFT. In particular, we consider the eigen

Fast Fourier Transforms, computation of DFT. is very important. Therefore this chapter treats fast Fourier transforms. A . (FFT) is an algorithm for computing the DFT. which needs only a relatively low number of arithmetic operations.
