What is Scilab ?
Scilab is free and open source software for numerical computation providing a powerful computing environment for engineering and scientific applications.
Scilab is released as open source under the CeCILL license (GPL compatible), and is available for download free of charge. Scilab is available under GNU/Linux, Mac OS X and Windows XP/Vista/7/8 (see system requirements).
What does Scilab do ?
Scilab 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.
A large number of functionalities is included in Scilab:
Maths & Simulation
For usual engineering and science applications including mathematical operations and data analysis.
2-D & 3-D Visualization
Graphics functions to visualize, annotate and export data and many ways to create and customize various types of plots and charts.
Algorithms to solve constrained and unconstrained continuous and discrete optimization problems.
Tools to perform data analysis and modeling
Control System Design & Analysis
Standard algorithms and tools for control system study
Visualize, analyze and filter signals in time and frequency domains.
Increase Scilab native functionalities and manage data exchanges with external tools.
Xcos - Hybrid dynamic systems modeler and simulator
Modeling mechanical systems, hydraulic circuits, control systems...
Scilab as a platform
Thanks to its ability to interconnect with third-party technologies and applications, Scilab can also act as a unique platform to bring together codes written in different programming languages in a single, unified language, thus facilitating their distribution, their back-up and use.
Why is it free ?
Because Scilab is open source
A entire community of contributors participates to the development of Scilab, from contribution to the code, development of external modules to the localization. The international scientific community, both academic and industrial spheres, invests in Scilab to gather recent scientific breakthroughs in the field of numerical computation.
Because Scilab is funded by Scilab Enterprises
Scilab Enterprises is the publisher and professional services provider of Scilab. Industrial companies benefit directly from this expertise to get the solution suited to their needs through a comprehensive range of support, migration, development services and the implementation of specific applications.
