Abstract : Four Fast Fourier Transform Programs have been written in FORTRAN. They give the Fourier Transform y(s), s=0 to s=(N-1) of the series (x(t), t=0 to t=(N-1) when all the data can fit in the memory of the computer. When N is a power of 2 the program FOUDEU is to be used. When N is a product of relatively prime factors the specialized program is DIANOD. When N is merely a product of factors, two programs are available: - TRISUP which performs the Gentleman-Sande method - TRITRA which performs the Cooley-Tuckey method. (Author)
