Genius Mathematics Tool – general purpose calculator

Genius Mathematics Tool (Genius) is a general purpose calculator program similar in some aspects to BC, MATLAB or Maple. It is useful both as a simple calculator and as a research or educational tool.

The language used in Genius Mathematics Tool is designed to be ‘mathematical’ in the sense that it should be ‘what you mean is what you get’. Of course that is not an entirely attainable goal. Genius Mathematics Tool features rationals, arbitrary precision integers and multiple precision floats using the GMP library. It handles complex numbers using Cartesian notation.

The software has good vector and matrix manipulation and can handle basic linear algebra. The programming language allows user defined functions, variables and modification of parameters.

Genius Mathematics Tool comes in two versions; a graphical GNOME version, which features an Integrated Development Environment (IDE) style interface and the ability to plot functions of one or two variables. There is also a command line version does not require GNOME, but naturally does not implement any feature that needs the graphical interface.

The syntax is very intuitive and is designed to mimic how mathematics is usually written.

Key Features

• Arbitrary precision ints, multiple precision floats.
• Rational numbers, stored as quotient and denominator.
• Complex numbers, stored in cartesian coordinates as usual.
• Math-like-looking expressions, tries to be as much a what-you-mean-is-what-Genius-understands, up to a limit of course.
• Matrix calculations / Linear Algebra, with many related functions.
• Number theory.
• Calculus, numerical and even very limited symbolic calculations.
• Statistics; all the basic statistical functions.
• Numerical equation solving, polynomial roots, etc.
• Combinatorics.
• Most common elementary / trigonometric functions.
• Modular arithmetic, including inversions and modular arithmetic on matrices
• A complete programming language, with automatic typing. In fact large part of Genius standard library is written in GEL.
• 2D Function line plots, standard 2D graphs of up to 10 functions at once, with possibility to export to EPS or PNG.
• Parametric plots, with possibility to export to EPS or PNG.
• 3D Function surface plots, with possibility to export to EPS or PNG.
• Slopefield/Vectorfield plotting.
• GUI IDE where you can edit and run/test your programs.
• Outputs matrices in LaTeX, Troff (eqn) or MathML.
• Plot point clouds.
