Frequently Asked Questions about surf()
Is the surf() 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 surf() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.
Do I need to install MATLAB to use surf()?
No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The surf() function requires no MATLAB® license or desktop software download.
What does surf() do?
3D surface plot. X, Y are 2D grids (from meshgrid), Z is height. It is a MATLAB®-compatible plotting function available in SimLab with the same calling syntax as MATLAB® — typically: surf(X, Y, Z).
Can I run surf() in my browser?
Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls surf(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
