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.
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.
