Simulating Diffusion in MATLAB with no Particle Overlap

Simulating Diffusion in MATLAB with no Particle Overlap

Often for my research I find the need to model systems of diffusing particles. The application can be aggregating nanoparticles, electrodeposition, or even simulations of molecular motors. These simulations are striking to me for their simplicity and ability produce qualitatively accurate results. All of this is done with a few simple (algorithmic) rules leading to a "logical geometric description" of the world.
