A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. The DFT is obtained by decomposing a … See more The development of fast algorithms for DFT can be traced to Carl Friedrich Gauss's unpublished work in 1805 when he needed it to interpolate the orbit of asteroids Pallas and Juno from sample observations. His … See more In many applications, the input data for the DFT are purely real, in which case the outputs satisfy the symmetry $${\displaystyle X_{N-k}=X_{k}^{*}}$$ and efficient FFT algorithms have been designed for this situation (see e.g. Sorensen, 1987). … See more As defined in the multidimensional DFT article, the multidimensional DFT transforms an array … See more An $${\textstyle O(N^{5/2}\log N)}$$ generalization to spherical harmonics on the sphere S with N nodes was described by Mohlenkamp, along with an algorithm conjectured (but not proven) to have $${\textstyle O(N^{2}\log ^{2}(N))}$$ complexity; … See more Let $${\displaystyle x_{0}}$$, …, $${\displaystyle x_{N-1}}$$ be complex numbers.
