SciLab is free and open-source software for numerical computations providing a powerful open computing environment for engineering and scientific application. It includes hundreds of mathematical functions. It has a high-level programming language allowing access to advanced data structures, 2-D and 3-D graphical functions.
SciLab software is distributed under the CeCILL license (GPL compatible). It has large numbers of functionalities: control, simulation, and optimization, signal processing. Xcos, the hybrid dynamic systems modeler and simulator is provided with the platform.
SciLab is an advanced application for all kinds of rather complex mathematical calculations. It allows the installation of modules to calculate differential equations, carry out linear algebra operations and perform polynomial and rational functions. It also allows us to program our own functions in languages such as FORTRAN, Java, and C++, and the possibility to edit graphs and export them in several formats.
