Generate random continuous test model
rss(n)
rss(n,p)
rss(n,p,m,s1,...,sn)
rss(n) generates an n-th
order model with one input and one output and returns the model in
the state-space object sys. The poles of sys are
random and stable with the possible exception of poles at s
= 0 (integrators).
rss(n,p) generates an nth
order model with one input and p outputs, and rss(n,p,m) generates
an n-th order model with m inputs
and p outputs. The output sys is
always a state-space model.
rss(n,p,m,s1,...,sn) generates an s1-by-...-by-sn
array of n-th order state-space models with m inputs
and p outputs.
Use tf, frd, or zpk to
convert the state-space object sys to transfer
function, frequency response, or zero-pole-gain form.
