This is a script package for modeling the Lotka-Volterra equations. There are 6 files in here, 3 functions and 3 codes to run these functions. I've helpfully named them in similar ways so you know which goes with which. lotka_ode.m and run_lotka_ode.m is your basic Lotka-Volterra equation package. This assumes no competition among the prey species and the population of the predator species is entirely dependant upon it. lotka_ode_c.m and run_lotka_ode_c.m is a slight tweak of the above scripts that adds the parameter c to the prey equation, to model intraspecific competition within your prey species. This assumes logistic growth in your prey species instead of exponential growth. lotka_ode2.m and run_lotka_ode2.m is a slightly different package that models interspecific competition among prey species. It is a system of 3 ODEs that is a modification upon the basic Lotka- Volterra equations which I adapted from a lesson from North Carolina State University. Happy modeling! Chandler Shaeffer
