poles of a three dimensional LTI array
sysarray are obtained as follows.
sysarray = tf(rss(2,1,1,3))
Model sysarray(:,:,1,1)
=======================
Transfer function:
-0.6201 s - 1.905
---------------------
s^2 + 5.672 s + 7.405
Model sysarray(:,:,2,1)
=======================
Transfer function:
0.4282 s^2 + 0.3706 s + 0.04264
-------------------------------
s^2 + 1.056 s + 0.1719
Model sysarray(:,:,3,1)
=======================
Transfer function:
