What have you tried so far? What specific problems are you having with your code? Have you looked at the examples in the ode45 doc for how to handle multiple equations?

f = @(t,y) [0.303*y(1)-0.557*y(1).^2+0.260*y(2).*y(1);...
0.0345*y(2)-1.18e-7*y(2).^2+3.55e-14*y(1).*y(2)];
Y0 = [0.0718,0.225];
tspan = [0 5];
[T,Y] = ode45(f,tspan,Y0);
plot(T,Y)
