clear
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.
