Q 4. With the aid of fourth order Runge-Kutta method, solvethe competing species model
[20 points]
defined by
dx =x(2 ? 0.4x ? 0.3y), x(0) = 4 dt
dy =y(1 ? 0.1y ? 0.3x), y(0) = 3 dt
where the populations x(t) and y(t) are measured in thousandsand t in years. Use a step size of 0.2 for 0 ? t ? 2 and plot thetrajectories of the populations with Matlab or GNU Octave.
