maximum. This can be handy when first examining a high order system. An example is
given below.
# Create a single-input, two-output system.
sys = [1/makepoly([1,0.1,1],"s");...
makepoly([1,1],"s")/makepoly([1,10],"s")]
# The automatic point selection is used.
sysg = freq(sys,{Fmin=0.01,Fmax=100,track})
# Now plot the result
ctrlplot(sysg,{bode})?
