UNIDFT: A package of optimized discrete fourier transforms

Abstract We present a package of FORTRAN 77 subprograms to compute the discrete Fourier transform of one-dimensional data sets. A large collection of specialized modules, assembled in a top-down scheme, guarantees high flexibility and efficiency. Comparative timings are given.
