Managing Data in the App
You can get information about each data set in the System Identification app by right-clicking the corresponding data icon.
Representing Time- and Frequency-Domain Data Using iddata Objects
Using the iddata constructor to represent time-domain and frequency-domain data and working with iddata objects.
Managing iddata Objects
The iddata object stores time-domain data or frequency-domain data and has several properties that specify the time or frequency values.
Representing Frequency-Response Data Using idfrd Objects
Using the idfrd constructor to represent frequency-response data and working with idfrd objects.
Manipulating Complex-Valued Data
Supported operations and limitations for handling complex data and commands for manipulating complex signals.
