Our verdict

Octave is the free answer to 'MATLAB alternative': its language is largely compatible with MATLAB, so most lab scripts for matrices, plotting and numerical methods run with few changes. The Windows installer is big (about 540 MB) because it bundles several Octave packages. There is no Simulink equivalent, and toolboxes are not one-to-one with MATLAB's.

FAQ

Which Octave Windows installer should I pick?

Use octave-11.3.0-w64-installer.exe. The 'w64-64' variant only helps with extremely large arrays (around 2 billion elements and ~32 GB RAM).
