Follow-up Comment #1, bug #68195 (group octave):

If someone wants to test it on MATLAB the code is:

-----------------------------

clear
clc
close all

load('octave')

fields = fieldnames(So_KF);

fields

num1=So_KF.num{1,1}.poly
den1=So_KF.den{1,1}.poly

So_KF_tf = tf(num1,den1)


num2=So_LQG.num{1,1}.poly
den2=So_LQG.den{1,1}.poly

So_LQG_tf = tf(num2,den2)

freq=[1:10:10e4];

figure
bode(So_LQG_tf,freq)

figure
bode(So_KF_tf,freq)

-----------------------------------
