Scilab

Scilab is a high level programming language that allows us to execute all types of mathematic calculations and combine various operations in a script to create a program through them.

Polynomial, matrixes, derivatives, integrals, equations or interpolation are some of the operations that can be solved using Scilab. It supports both normal and scientific calculations.

Like in any other programming language, operations in Scilab are described through the use of variables, operators, functions, flow control, etc. Its strong point is graphic generation in two and three dimensions (it is capable of creating a PostScript file from them).
