Maxima is a system for the manipulation of symbolic and numerical expressions, including differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors. Maxima yields high ... [More] precision numeric results by using exact fractions, arbitrary precision integers, and variable precision floating point numbers. Maxima can plot functions and data in two and three dimensions. The Maxima source code can be compiled on many systems, including Windows, Linux, and MacOS X. The source code for all systems and precompiled binaries for Windows and Linux are available at the SourceForge file manager. [Less]

cl-cffi-gtk is a Lisp binding to the GTK+ (GIMP Toolkit) which is a library for creating graphical user interfaces. It is licensed using the LGPL which has been adopted with a preamble that clarifies the terms for use with Lisp programs and is referred as the LLGPL. This work is based on the cl-gtk2 ... [More] library which has been developed by Kalyanov Dmitry and already is a fairly complete Lisp binding to GTK+. The focus of this work is to document the library more complete and to do the implementation as consistent as possible. Most informations about GTK+ can be gained by reading the C documentation. Therefore, the C documentation from www.gtk.org is included into the Lisp files to document the Lisp binding to the GTK+ library. Examples of the usage are included in demos and tutorial examples.
