Question

Hi there! I need help with plotting in Matlab. I need to lot the real and imaginary parts of the following equation. For zeta = 0.01, and 0.02.  I keep getting errors in my code when producing the plots. Any help with setting up the code and producing plots would be greatly appreciated, and will rate HIGHEST POSSIBLE for results. Thank you!

H(omega) = 1 - (omega/omega n)2/[1 - (omega/omega n)2]2 + [2 zeta omega/omega n]2 - i 2 zeta omega/omega n/[1 - (omega/omega n)2]2 + [2 zeta omega/omega n]2 the Z = x -iy complex format.

Explanation / Answer

if you want to plot only real part of H vs w then use

plot(w,real(H))

if you wnt to plot only imaginary part of H vs w then use

plot(w,imag(H))

if you want magnitude of H vs w then use

plot(w,abs(H))
