del2()

Core Math

del2() is a MATLAB®-compatible core math function for discrete laplacian of a 2-d matrix. returns a matrix of the same size where each element is the average of its neighbors minus the element itself, divided by 4. boundary elements use only available neighbors. Run it online in your browser with SimLab — free, no install, no license required.

Frequently Asked Questions about del2()

Is the del2() 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 del2() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.

Do I need to install MATLAB to use del2()?

No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The del2() function requires no MATLAB® license or desktop software download.

What does del2() do?

Discrete Laplacian of a 2-D matrix. Returns a matrix of the same size where each element is the average of its neighbors minus the element itself, divided by 4. Boundary elements use only available neighbors. It is a MATLAB®-compatible core math function available in SimLab with the same calling syntax as MATLAB® — typically: del2(F).

Can I run del2() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls del2(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
