Frequently Asked Questions about minreal()

Is the minreal() function free to use in SimLab?

The browser workspace requires no MATLAB® license or installation. Connected features require network access and may have account, tier, availability, or usage limits. You can open minreal() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.

Do I need to install MATLAB to use minreal()?

No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The minreal() function requires no MATLAB® license or desktop software download.

What does minreal() do?

Minimal realization via pole-zero cancellation. Removes common poles and zeros from a transfer function within tolerance 1e-6. Returns simplified TF. It is a MATLAB®-compatible control systems function available in SimLab with the same calling syntax as MATLAB® — typically: minreal(sys).

Can I run minreal() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls minreal(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
