What appropriate code should i use on line 13?
syms r K E y
eqn = r*(1-y/K)*y-E*y==0;
S = solve(eqn);
y1=S(1);
y2=S(2);
dydt=@(y, E, r, k) r .* (1-y/K) .* y-E*y;
h=0.01;
E=1;
r=2;
K=1;
y = y1-h:h:subs(y2)+h;
subplot(1, 1, 1)
plot(y, dydt(y, E, r, K)) %Plot not working
title('f(y) Function')
xlabel('y')
ylabel('dy/dt')
grid on

%if true
plot(y, double(subs(dydt(y, E, r,K))));
