2 Choosing Your System Identification Strategy
ans =
1.0000 -0.8441 -0.1539 0.2278 0.1239
Similarly, to access the uncertainties in these param eter estimates, type
the following command:
m_arx.da
ans =
0 0.0357 0 .050 2 0.0438 0.0294
Property names are not case sensitive. You do not need to type the entire
property name if the rst few letters uniquely identify the property.
To change property v alues for an ex isting model obje ct, use the
set command
or dot no tat io n . For example, to change the input delays for all t hre e input
channels to
[1 1 1], t ype the fo ll owing at t he prompt:
set(m_arx,'nk',[1 1 1])
or equivalently
m_arx.nk = [1 1 1]
Some model properties, such as Algorithm, are structures. To access the
elds in this structure, use the following syntax:
model.algorithm.PropertyName
where Prope rtyName represents any of the A lgorithm elds. For ex ample,
to change the maximum number o f iterations using the
MaxIter property,
type the following comm and:
m_arx.algorithm.MaxIter=50
To verify the new property value, type the following:
m_arx.algorithm.MaxIter
Note PropertyName refers to elds in a structure and is case sensitive. You
