Comparison
PolySim OS vs GNU Octave
Octave is the free, MATLAB-compatible option, and it's excellent if you already think in .m files. But it's still an install-and-script desktop environment. PolySim is interactive and browser-native, with hundreds of models you can run and adjust visually — and it exports MATLAB-compatible code when you want it.
