Purpose Access/query LTI property values
Syntax Value = get(sys,'PropertyName')
get(sys)
Struct = get(sys)
Description Value = get(sys,'PropertyName') returns the current value of the property
PropertyName oftheLTImodel sys. The string 'PropertyName' canbe the full
propertyname(forexample,
'UserData') oranyunambiguouscase-insensitive
abbreviation (for example,
'user'). You can specify any generic LTI property,
or any property specific to the model
sys (see “LTI Properties” for details on
generic and model-specific LTI properties).
Struct = get(sys) converts the TF, SS, or ZPK object sys into a standard
MATLAB structure with the property names as field names and the property
values as field values.
Without left-hand argument,
get(sys)
displays all properties of sys and their values.
Example Consider the discrete-time SISO transfer function defined by
h = tf(1,[1 2],0.1,'inputname','voltage','user','hello')
You can display all LTI properties of h with
get(h)
num = {[0 1]}
den = {[1 2]}

Ts = 0.1
InputDelay = 0
OutputDelay = 0
