I'm relatively new to control systems.

I got to know how critically damped system looks like in Nyquist plot (same gain and phase cross over frequencies. PS. correct me if I'm wrong) and Bode plot thanks to tge Octave online simulator, but I'm really curious to know what a Nyquist plot for a undamped system looks like if it exists. If it doesn't exist, why not?

I tried to plotting plots for

num = [1]; den = [1,0,5]; s = tf(num,den); bode(s) # exists nyquist(s) # throws error polar(s) # throws error 

PS. I know the system would be unstable, just curious.
