Purpose Set or modify LTI model properties
Syntax set(sys,'Property',Value)
set(sys,'Property1',Value1,'Property2',Value2,...)
set(sys,'Property')
set(sys)
Description set isusedtosetormodifythepropertiesof anLTImodel(see“LTIProperties”
on page 2-26 for background on LTI properties). Like its Handle Graphics
counterpart,
set uses property name/property value pairs to update property
values.
set(sys,'Property',Value) assigns the value Value to the property of the
LTI model
sys specified by the string 'Property'. This string can be the full
propertyname(forexample,
'UserData')or anyunambiguouscase-insensitive
abbreviation (forexample,
'user'). The specified property must be compatible
with the model type. For example, if
sys is a transfer function, Variable is a
valid property but
StateName is not (see “Model-Specific Properties” on page
2-28 for details).
set(sys,'Property1',Value1,'Property2',Value2,...) sets multiple
property values with a single statement. Each property name/property value
pair updates one pa rticular property.
set(sys,'Property') displays admissible values for the property specified by
'Property'. See “Property Values” below for an overview of legitimate LTI
property values.
set(sys) displays all assignable properties of sys and their admissible values.
Example Consider the SISO state-space model created by
sys = ss(1,2,3,4);
You can add an input delay of 0.1 second, lab el the input as torque, reset the
matrix to zero, and st ore it s DC gain in the
'Userdata' property by
set(sys,'inputd',0.1,'inputn','torque','d',0,'user',dcgain(sys))
