C1 = 20000;
C2 = linspace(0,26,5500);
k1 = 0.5;
k2 = 5;
n1 = 0;
n2 = 0;
nm = 0;
D = -1;
O = 1;
gam = 0.01;
alph = 0;
for ii=1:length(C2)
w = linspace(-10,10,5500);
k1eff = k1.*(1+C2);
TA = w./(k1eff./2);
TB = w./(gam./2);
Y1 = (-2.*1i.*sqrt(C1))./(sqrt(gam).*((1+C2).*(1-1i.*TA).*(1-1i.*TB)+C1));
Y2 = (-2.*sqrt(C1.*C2))./(sqrt(gam).*((1+C2).*(1-1i.*TA).*(1-1i.*TB)+C1));
Y3 = (2.*(1+C2).*(1-1i.*TA))./(sqrt(gam).*((1+C2).*(1-1i.*TA).*(1-1i.*TB)+C1));
AY1 = abs(Y1).^2;
AY2 = abs(Y2).^2;
AY3 = abs(Y3).^2;
Sbb = 2*pi.*(AY1.*(n1 + 0.5) + AY2.*(n2 + 0.5) + AY3.*(nm + 0.5));
figure(1)
plot(TB,Sbb)
drawnow limitrate
%ylim([0,30])
set(gca,'FontSize',13)
xlabel('\Theta_B')
ylabel('S_{bb}')
%ylim([0,5])
end
I am trying to plot my Sbb as a function of TB for each step of the loop. Upon executing the code above however I see a curve with two peaks with different heights but the graph isn't changing over time. Much help would be appreciated. Thank you in advance.

Nothing in your for loop depends on the loop variable ii, so why would you expect the plot to change?
