by typing
g = tf([1 0.1 7.5],[1 0.12 9 0 0]);
bode(g)
To plot the response on a wider frequency range, for example, from 0.1 to 100
rad/sec, type
bode(g,{0.1 , 100})
You can also discretize this system using zero-order hold and the sample time
second, and compare the continuous and discretized responses by
typing
gd = c2d(g,0.5)
