Import time-domain data into the System Identification app
Import frequency-domain input-output data and frequency-response data into the System Identification app.
Creating input data with specific characteristics and simulating the output data from a model.
Represent time-domain, time-series, and frequency-domain data.
How to create idfrd objects.
The toolbox provides limited support for nonuniformly sampled data.
Specify time between successive data samples.
You can get information about each data set in the System Identification app by right-clicking the corresponding data icon.
iddata object stores time-domain data or frequency-domain data and has several properties that specify the time or frequency values.
Subreferencing and concatenating idfrd objects
Supported operations and limitations for handling complex data and commands for manipulating complex signals.
