Description

solvePoissonSOR.m is an efficient, lightweight function that solves the Poisson equation using Successive Overrelaxation (SOR) with Chebyshev acceleration to speed-up convergence. Dirichlet boundary conditions are used to provide a unique solution.

Worked right out of the box! I used it to regenerate an image based on its Laplacian.

I also tried

http://www.mathworks.com.au/matlabcentral/fileexchange/21472-2d-fast-poisson-solver

but I found that its documentation was less clear, the API inconvenient (I had to edit a file to get my function in) and I got a dynamic load error on some fft module which hung MATLAB, though I think this is a MATLAB problem not the contributed codes.
