FEMLISP is a Mathematics Library which solves partial differential equations with the help of the finite element method (FEM).Source code is available at the project site, CVS access via savannah.nongnu.org. I am thinking about moving it to common-lisp.net (Nicolas Neuss).

A Common Lisp library to do Fast Fourier Transform on a multi-dimensional array of numbers. See Bordeaux-FFT for a faster implementation for one-dimensional arrays.This library is by Patrick Stein.The array can be any number of dimensions, but each dimension must be a power-of-two in size.Here is a simple example on a two-dimensional input buffer. (require :asdf) (asdf:operate 'asdf:load-op 'fft) (defparameter *buf* #2A((1 2 3 4)(5 6 7 8))) (let ((transformed (fft:fft *buf*))) (fft:ifft transformed)) Here is an example using the a parallelized version that uses pcall which, in turn, uses Bordeaux-Threads: (require :asdf) (asdf:operate 'asdf:load-op 'pfft) (defparameter *buf* #2A((1 2 3 4)(5 6 7 8))) (let ((transformed (pfft:pfft *buf*))) (pfft:pifft transformed)) For a more complete description, see the home page.

The GNU Scientific Library for Lisp (GSLL) allows you to use the GNU Scientific Library (GSL) from Common Lisp. This library provides a full range of common mathematics operations useful to scientific and engineering applications. The design of the GSLL interface is such that access to most of the GSL library is possible in a Lisp-natural way; the intent is that the user not be hampered by the restrictions of the C language in which GSL has been written. GSLL thus provides interactive use of GSL for getting quick answers, even for someone not intending to program in Lisp. Topics include: roots of polynomials, special functions, vector and matrix operations, permutations, sorting, BLAS support, linear algebra, eigensystems, fast Fourier transforms, quadrature, random numbers, quasi-random sequences, random distributions, statistics, histograms, N-tuples, Monte Carlo integration, simulated annealing, differential equations, interpolation, numerical differentiation, chebyshev approximation, series acceleration, discrete Hankel transforms, root-finding, minimization least-squares fitting, IEEE floating-point, discrete wavelet transforms.For more information see the project website.Available with Quicklisp.Page on GitLab
