Scilab free numerical computation

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 theCeCILL 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. 
• Optimization
  Algorithms to solve constrained and unconstrained continuous and discrete optimization problems. 
• Statistics
  Tools to perform data analysis and modeling 
• Control System Design & Analysis
  Standard algorithms and tools for control system study 
• Signal Processing
  Visualize, analyze and filter signals in time and frequency domains. 
• Application Development
  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.
