What Is Scilab?

Scilab is a free, open-source software package for numerical computing, made for engineers and scientists. It handles matrix maths, signal processing, and simulation, and it comes with Xcos, a visual tool for building and testing dynamic systems. It comes from a worldwide community, and it is used in classrooms and labs around the whole world today.

It suits students and engineers who need a strong, free maths platform. You can write scripts, draw plots, and model control systems without a paid licence. It runs on Windows 10 and 11, stays free for every use, and works fully offline. It also reads and writes data in common formats, so results move easily into spreadsheets and reports.

Key Features

Matrix computing: solve linear algebra and large numerical problems with simple commands.
Xcos modeller: build and simulate dynamic systems by dragging blocks onto a canvas.
2D and 3D plots: draw charts, surfaces, and animations from your data.
Signal processing: filter signals, analyse spectra, and test control systems.
Scripting language: write scripts in a MATLAB-like language to repeat any calculation.
Toolboxes: add modules for image processing, optimisation, and more.
Free licence: use it for study, research, and commercial work at no cost.

System Requirements

Operating system: Windows 10 or Windows 11, 64-bit.
Processor: any modern 64-bit processor, even a modest one.
Memory: at least 2 GB of RAM, with 4 GB recommended for large simulations.
Disk space: around 1 GB for the app and its toolboxes.
Network: an internet connection for the download and for extra toolboxes; computing works offline.
Display: any screen, with a larger display recommended for Xcos diagrams and plots.

Open Scilab from the Start menu and wait for the console to appear.
Type A = [1 2; 3 4] and press Enter to create a small matrix.
Type inv(A) and press Enter to see the inverse of that matrix.
Type x = 0:0.1:10; y = sin(x); to create data for a plot.
Type plot(x, y) and press Enter to draw a sine wave in a new window.
Open Xcos from the Applications menu to try a visual simulation.
Save your commands in a script file with the .sci extension for later use.
