Discrete Laplacian - MATLAB del2 - MathWorks
www.mathworks.com › help › matlabCalculate the Laplacian of this function using del2. The spacing between the points in U is equal in all directions, so you can specify a single spacing input, h. h = 0.25; L = 4*del2 (U,h); Analytically, the Laplacian of this function is equal to Δ U ( x, y) = 4 x 2 + 4 y 2. Plot the discrete Laplacian, L.
