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 linguagem de programação.
O software inclui o Xcos, um editor gráfico para modelagem e simulação de sistemas dinâmicos híbridos, e oferece extensas bibliotecas para álgebra linear, otimização e processamento de sinaisSua arquitetura aberta suporta a integração com C, C++ e Java, permitindo que os usuários expandam a funcionalidade por meio de conjuntos de ferramentas especializados e vinculação de código externo.
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 prototipagem rápida 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.
