1 Data Processing
If you a re working with multiple inputs, you also have the option of
storing the contribution by each input as an independent experiment in a
multiexperiment data set. To transform an
idfrd object with the n ame
idfrdobj to a multiexperiment data set datf, where each experiment
corresponds to each of the inputs in
idfrdobj
datf = iddata(idfrdobj,'me')
In this example, the additional argument 'me' speci fies that multiple
experiments a re created.
By default, transfo rmation from frequency-response to frequency-domain
data strips away frequencies where the response is
inf or NaN. To pres erve
the entire frequency vector, use
datf = iddata(idfrdobj,'inf').Formore
information, type
help idfrd/idd ata.

Transformin g from time-dom ain or frequency-dom ain data to
frequency-response data is equivalent to creating a frequency-response model
from the data. For more information, see “Identifying Frequency-Response
Models” on page 3-2.
