Fourgen: A fast fourier transform program generator

Title of program: FOURGEN Catalogue Id: ABUO_v1_0 Nature of problem FOURGEN generates specialized fast-Fourier-analysis codes based on Hockney general-purpose code FOUR67. Each code is capable of performing one of the four transform types (sine analysis and synthesis, cosine analysis and synthesis, periodic analysis, and periodic synthesis) on a real vector of fixed length.
