You can use ode45() to solve such a system of ODEs.
ic = [2; 4];
xspan = [0 1];
[x, Q] = ode45(@odeFun, xspan, ic);
y_sol = Q(:,1);
z_sol = Q(:,2);
plot(x, Q);
legend({'y', 'z'}, 'FontSize', 16);
function dQdx = odeFun(x, Q)
% Q(1) <=> y, Q(2) <=> z
y = Q(1);
z = Q(2);
dydx = -2*y + 4*exp(-x) + exp(-1000*z^2);
dzdx = -y*z^2/3;
dQdx = [dydx; dzdx];
end
