fd_predator_prey, a MATLAB code which applies the finite difference method (FDM) to a predator-prey system with time dependence and no spatial variation.
PP_100 uses 100 timesteps, which are not enough.
pp_1000 uses 1000 timesteps, which are enough to see that there is a pattern, but not enough to catch the pattern accurately.
pp_10000 uses 10000 timesteps, which are enough.
