Refer to [BoB91] in Appendix A, 

.

1.

Let a system H be a 2-input/2-output system:

tf=makepoly([1,2],"s")/...

polynomial([0,-2.334,-12],"s")

H = [tf, 2*tf; tf*tf, tf+3];

[outputs,inputs]=size(H)

2.

Now plot the singular values of the system between 0.01 and 100 Hz 
using 

svplot( )

:

svplot(H,{Fmin=0.01,Fmax=100})

The result is shown in Figure 3-1. For a discussion of 

svplot( )

 syntax, 

refer to the Xmath Help.
