Sogol

Math Assistant and Hypertext Notepad for Engineers and Scientists using Windows. Assists with calculating networks of formulae, dynamic simulations, equation solutions, differential, multiple equations and unknowns, with built-in script language. Useful for engineering and scientific computations, trying out algorithms, plotting results, quantitative brain-storming, and documenting problem solutions.
