Frequently Asked Questions about fminbnd()

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

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

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

What does fminbnd() do?

Find a local minimizer of a scalar function f on the bounded interval [a, b] using Brent golden-section / parabolic interpolation. It is a MATLAB®-compatible optimization function available in SimLab with the same calling syntax as MATLAB® — typically: x = fminbnd(f, a, b).

Can I run fminbnd() in my browser?

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