Scilab is an open source, cross-platform numerical computational package and a high-level, numerically oriented programming language. It can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, numerical optimization, and modeling and simulation of explicit and implicit dynamical systems. MATLAB code, which is similar in syntax, can be converted to Scilab. Scilab is one of several open source alternatives to MATLAB.

Scilab is a matrix-based scientific software package. Scilab contains hundreds of built-in mathematical functions, rich data structures (including polynomials, rationals,linear systems, lists, etc...) and comes with a number of specific toolboxes for control, signal processing and more.

Command Line Interpreter (CLI) for Scilab is available.

Scilab 5 is governed by the CeCILL license (GPL compatible) abiding by the rules of distribution of free software.
