Frequently Asked Questions about nyquist()

Is the nyquist() 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 nyquist() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.

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

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

What does nyquist() do?

Nyquist frequency response plot. Plots the real vs imaginary parts of the open-loop frequency response for stability analysis. It is a MATLAB®-compatible control systems function available in SimLab with the same calling syntax as MATLAB® — typically: nyquist(H).

Can I run nyquist() in my browser?

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