Creating a Model Change History

Simulink allows you to create and store a record of changes to a model in the model itself. Simulink compiles the history automatically from comments that you or other users enter when they save changes to a model.

Logging Changes

To start a change history, select the "Prompt for Comments When Save" option from the History pane on the Simulink Model Properties dialog box. The next time you save the model, Simulink displays a Log Change dialog box.


If you want to add an item to the model's change history, enter the item in the Modified Comments edit field and click the Save button. If you do not want to enter an item for this session, uncheck the Include "Modified Contents" in "Modified History" option. If you want to discontinue change logging, uncheck the Show this dialog box next time when save option.

Editing the Change History

To edit the change history for a model, click the Edit button on the Simulink Model Properties dialog box. Simulink displays the model's history in a Modification History dialog box.


Edit the history displayed in the dialog and select Apply or OK to save the changes.
