Data Supported by Grey-Box Models

You can estimate both continuous-time or discrete-time grey-box models for data with the following characteristics:

• Time-domain or frequency-domain data, including time-series data with no inputs.

  Note

  Nonlinear grey-box models support only time-domain data.

• Single-output or multiple-output data

You must first import your data into the MATLAB^® workspace. You must represent your data as an iddata or idfrd object. For more information about preparing data for identification, see Data Preparation.
