Linearizing the Model Using Simulink Control Design Commands

We can reproduce these results using the command line interface of Simulink Control

Design.

model = 'scdmrate';

io(1) = linio('scdmrate/Constant',1,'input');

io(2) = linio('scdmrate/sysTs2',1,'openoutput');

sys = zpk(linearize(model,io))

sys =

From input "Constant" to output "sysTs2":
