Octave

Octave is a free, open-source software environment used for numerical computation and data analysis. It allows users to perform complex mathematical calculations, create algorithms, and visualize data through graphs and plots. Similar to commercial tools like MATLAB, Octave is widely used in engineering, scientific research, and academic settings for tasks such as modeling, simulation, and data processing. Its syntax is largely compatible with MATLAB, making it accessible for those familiar with that language, and it provides a powerful platform for technical computing without the cost of proprietary software.
