Frequently Asked Questions about xcorr()

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

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

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

What does xcorr() do?

Cross-correlation (or autocorrelation if y omitted). It is a MATLAB®-compatible signal processing function available in SimLab with the same calling syntax as MATLAB® — typically: xcorr(x).

Can I run xcorr() in my browser?

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