Free and open-source software for numerical computation providing a powerful computing environment for engineering and scientific applications: Scilab a high-level numerical computational platform maintained by Dassault Systèmes, designed for engineering and scientific data processing. It provides a comprehensive environment for matrix-based calculations, 2D and 3D visualization, and algorithm development through a dedicated programming language.
The software includes Xcos, a graphical editor for modeling and simulating hybrid dynamical systems, and offers extensive libraries for linear algebra, optimization, and signal processing. Its open architecture supports integration with C, C++, and Java, allowing users to extend functionality through specialized toolboxes and external code linking.
Professionals in engineering, science, and manufacturing apply Scilab to execute complex simulations and automate technical workflows. In control systems engineering, it is used to model plant dynamics and design feedback loops for industrial automation via Xcos. Scientists utilize its statistical and optimization toolboxes for large-scale data analysis and the validation of mathematical models in research environments. Quality and manufacturing experts leverage the platform to implement statistical process control and optimize production parameters, facilitating rapid prototyping and system analysis without the overhead of proprietary software licenses.
One of the very non-online tool we list here. Exists for windows, Linux and MacOS and available under GNU GPL 2.0 on Github.
