matlab file set to numerically integrate a set of ode equations and store the extrema over a parameter range in effect generating a one-parameter bifurcation diagram rm.m are the equations, in this case the three-dimensional food chain rosenzweig-macarthur model process.m is the file where integration is done, over a range of one parameter events.m gives the event "extremum" if these files are used for a different set of ode's all three files must be adapted
