I tried plotting modz as a function of log10w but there is no line on my graph w=0.001:1000 modz=sqrt((w.^0.5 + 20*cos(pi/8)*w.^0.25 + 100)/(1+ 2*cos(pi/8)*w.^0.25 +w.^0.5)) W=log10(w) figure(3) plot(W,modz)

You need to vectorise (do element-wise calculations) in your ‘modz’ calculation. This means substituting ‘./’ for /:
modz=sqrt((w.^0.5 + 20*cos(pi/8)*w.^0.25 + 100)./(1+ 2*cos(pi/8)*w.^0.25 +w.^0.5));

That will work.
