I use pzplot() function to plot the Pole-zero map(figure 1), and the legend shows the every poles' information once the narrow click the figure. And I want to storage the infrom into a variety. so could you help me how to do?

The resonant frequencies (poles) are given by the absolute value of the poles of the continuous system.
Example —
H = tf([1 -1],[1 1 0.3],0.1); % Discrete System
pzmap(H)
grid on
axis equal
Hc = d2c(H); % Convert To Continuous
fr = abs(pole(Hc)); % Resonant Frequencies
I know of no other way to do what you want.
