clear

clc

t = 0: 0.01 : 2;

omega_n = 10;

omega = 0:0.1:20;

r = omega/omega_n;

XY1 = sqrt((1+(2*zeta1*r).^2)/((1-r.^2).^2+(2*zeta1*r).^2))

XY1 = 0.4739

plot(r,XY1)

I cannot understand why the XY1 does not have same dimension as r has.

Could you explain why and fix the codes to plot the r vs XY1 graph?

omega_n = 10;

omega = 0:0.1:20;

zeta1 = 1.0;

r = omega./omega_n;

XY1 = sqrt((1+(2*zeta1*r).^2)./((1-r.^2).^2+(2*zeta1*r).^2));

plot(r,XY1)
