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.

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. Execution happens locally in your browser — no data leaves your machine.
