corr-spec I simulate 2D diffusion of N particles on a grid to understand Fluorescence Correlation Spectroscopy (FCS). Check it out here! Parameters that can be played around with: N (Number of particles) D (Diffusion coefficient of the particles) References: C++ Model of 2D diffusion. Heinemann, Vogel and Schwille, 2013.
