About

Scilab is free and open source software for numerical computation providing a powerful computing environment for engineering and scientific applications. 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 2-D & 3-D Visualization: Graphics functions to visualize, annotate and export data Optimization: Algorithms to solve constrained and unconstrained continuous and discrete 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 Xcos - Hybrid dynamic systems modeler and simulator: Modeling physical systems, control systems 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.
