    Computational methods are used extensively in the analysis and real time solution of model problems in electrophysics. An Interactive Graphical Language (IGL), developed at the Polytechnic, is used throughout these web pages to provide interactive numerical and graphic solutions. The most recent Java version of IGL has been written primarily by Prof J Latourrette, without whom many of the following web pages would not have been possible. For comments and corrections relating to Java versions of Igl write to Prof. J. Latourrette

IGL provides a  means for writing and executing mathematical algorithms using a built in set of primitive IGL commands, each executable by a single keystroke. Command sequences are collected in strings (sub-programs) and stored in source files, whose parameters can be interactively adjusted. Such strings are executable by the user in real time and the resulting calculations may be graphically displayed.

    An IGL tutorial provides a brief introduction to IGL and to its capabilities for algorithmic computation of solutions to mathematical equations and their graphic display.

    Examples of Algorithmic Techniques using IGL are provided for representation of mathematical functions, as well as for formulation and execution of algorithms yielding real time graphic solutions of mathematical problems.
