Weak formulation, where w ( x) is the weight function, yields: ∫ 0 1 w ( x) ∂ 2 η ∂ t 2 d x − ∫ 0 1 w ( x) ∂ 2 η ∂ x 2 d x = 0. ∫ 0 1 w ∂ 2 η ∂ t 2 d x − ∫ 0 ... The Following is my Matlab code to simulate a 2D wave equation with a Gaussian source at center using FDM.I used imagesc function to output the wave. The wave seems to spread out from the center, but very slowly. It seems like I messed it upp somewhere. And the output is very pixelated. What am I doing wrong?
