Representing Frequency-Response Data Using idfrd Objects
response and f are variables in the MATLAB Workspace browser,
representing the frequency-response data and frequency values, respectively.
MATLAB returns the following object properties and values:
ans =
Name: ''
Frequency: [10 0x1 double]
ResponseData: [1x1x100 double]
SpectrumData: []
CovarianceData: []
NoiseCovariance: []
Units: 'rad/s '
Ts: 0.0800
InputDelay: 0
EstimationInfo: [1x1 struct]
InputName: {'u 1'}
OutputName: {'y 1'}
InputUnit: {'' }
OutputUnit: {'' }

For a com plete description of all idfrd object properties, se e the idfrd
reference page o r type idprops idfrd at the prompt.
To change property v alues for an existing
idfrd object, use the set command
or dot notation. For example, to change the name of the
idfrd object, type
the following command sequence at the prompt:
% Set the name of the f_d ata object
set(fr_data,'name','DC_Converter')
% Get fr_data properties and values
get(fr_data)
Property names are not case sensitive. You do not need to type the entire
property name if the first few letters uniquely identify the property.
