FFTPACK is a library of Fortran routines designed for performing Fast Fourier Transforms (FFTs) and related computations. It was developed to provide efficient algorithms for computing the discrete Fourier transform (DFT) and its inverse, which are fundamental processes in various applications within signal processing, image analysis, solving partial differential equations, and many other fields.
