A matlab coding problem

The Lotka-Volterra predator prey model is described by two coupled differential equations and as indicated in the https://en.wikipedia.org/wiki/Lotka%E2%80%93Volterra_equations

Solve these coupled differential equations for when initial prey and predator numbers are 8 and 1, respectively. Try and obtain solutions for t = 100 and dt = 1, 0.5 and 0.1. Allow the function to be called such that it solves this model using the Euler method or the RK2 method.

Your function must produce two annotated plots: the first one should display the predator and prey populations vs. time, while the second should be a "phase plot" of number of predators vs. number of prey.
