Applied Numerical Methods with MATLAB for Engineers and Scientists

Employ ode45 to solve the following set of nonlinear ODEs from t = 0 to 20:
$\frac{d y_1}{d t}=1.2 y_1-0.6 y_1 y_2 \quad \quad \quad \frac{d y_2}{d t}=-0.8 y_2+0.3 y_1 y_2$
where $y_1 = 2 \text{ and } y_2 = 1$ at t = 0. Such equations are referred to as predator-prey equations.
