When to Use the App vs. the Command Line
After installing the System Identification Toolbox™ product, you can start the System Identification app or work at the command line.
You can work either in the app or at the command line to preprocess data, and estimate, validate, and compare models.
The following operations are available only at the command line:
Generating input and output data (see
Estimating coefficients of linear and nonlinear ordinary differential or difference equations (grey-box models).
Using recursive online estimation methods. For more information, see topics about estimating linear models recursively on the Online Estimation page.
Conversions to LTI objects require the Control System Toolbox software.
New users should start by using the app to become familiar with
the product. To open the app, on the Apps tab
of MATLAB® desktop, in the Apps section,
click System Identification. Alternatively,
systemIdentification in the MATLAB Command
To work at the command line, type the commands directly in the MATLAB Command
Window. For more information about a command, type
doc command_name in
the MATLAB Command Window.
