08-Jan-2022 10:36:11 trapezoidal_fixed_test(): MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2 Test trapezoidal_fixed() on several ODE's. We use a constant stepsize. predator_prey_trapezoidal_fixed(): A pair of ordinary differential equations for a population of predators and prey are solved using trapezoidal_fixed(). The exact solution shows periodic behavior, with a fixed period and amplitude.
