Maxima is a computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more. For example, Maxima solves x^2-r*x-s^2-r*s=0, giving the symbolic results [x=r+s, x=-s]. It can also calculate with exact integers and fractions, native floating-point, and high-precision big floats. Maxima has user-friendly front-ends, an online manual, plotting commands, and numerical...

Tkgames is a site for games written using the powerful tcl/tk language. These include my original tesselation puzzle Polypuzzle, and recent additions Hearts, Spider, Yahtzee and the tooo addictive, Tktk.

A library for multiple precision math - arbitrarily large numbers - in TCL. Based on the original mpexpr library from Tom Poindexter.

The Yupana was an ancient calculating device of the Incas. This simple program compares different theories: - positional notation * Base 10 by H. Wassen (representation, addition) * Base 10 by C. Radicati di Primeglio (representation, addition, subtraction, multiplication) * Base 10 by W. Burns Glynn (representation, addition, multiplication) * Base 40 by N. De Pasquale (representation) - sign-value notation * Powers of ten by C. Florio ...

surfit is an open source and free gridding and contouring software. surfit can do interpolation/approximation of points, contours and surfaces, can take fault lines and trend surfaces into account, can use inequalities and other conditions. Supports a lo

ASCEND is a modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provid

The main scope of the program is to take Thermo-Calc or Dictra (both registered trademarks) and transform them into nicely formatted encapsulated postscript diagrams, generated by gnuplot. But exp2plt can also be used as a graphical interface to gnuplot.

Tcl binding to levmar library implementing Levenberg-Marquardt optimization algorithm often used in data fitting. Levmartcl is a standard Tcl extension providing command interface to levmar functionality. This library is only a wrapper of <levmar> which actually performs the work. See the <levmar> home site for details: http://www.ics.forth.gr/~lourakis/levmar/

Tcl n-dimensional array processor

RReportGenerator aims to provide a simple and user-friendly multi-platform graphical user interface (GUI) allowing to run routine statistical analysis using R via predefined analysis scenarios to produce reports in pdf-format.

Ordinary Differential Equation (ODE) solver for Tcl. Handles both stiff and non-stiff sets of equations; does time-evolved initial value problems and root finding. Based on the popular Lawrence Livermore solver LSODE.

This project aims to develop open source psychometric data analysis software, including estimation software for Rasch and Item Response Theory (IRT) models for both dichotomous and polytomous test items.

tkalc is a pocket calculator for developers and IP network operators. Arbitrary arithmetic/logical expressions can be entered very quickly. The result is then simultaneously displayed in decimal, hexadecimal, octal, binary, ASCII, IP address, and boolean.

Ytk is a Tcl/Tk program which adds menus, buttons and features to the basic command line driven Yorick program and language. It also enables usage of all Tcl/Tk widgets and functions including buttons, sliders, checkboxes, and other typical TK widgets to

SigLab is a signal calculator for Scilab. Its goal is to ease the analysis of signal processing simulation results. It allows to view and to manipulate monodimensional signals in a interactive and easy way.

GNU Autoconf, Automake and Libtool scripts and makefiles for the Open CASCADE solid modeler. http://www.opencascade.org

Project provides some Tcl/Tk procedure for manipulating Biology data. And, attributed to the clarity of the Tcl code, it is also useful for education.
