Frequently Asked Questions about graythresh()
Is the graythresh() 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 graythresh() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.
Do I need to install MATLAB to use graythresh()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The graythresh() function requires no MATLAB® license or desktop software download.
What does graythresh() do?
Compute a global image threshold using Otsu's method (returns a value in [0,1]). It is a MATLAB®-compatible computer vision function available in SimLab with the same calling syntax as MATLAB® — typically: level = graythresh(img).
Can I run graythresh() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls graythresh(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
