How to discard unsaved changes to a Data Dictionary?

In the tempdir there is an SLDDC file that stores the changes that have not been saved to the SLDD file. If MATLAB crashes, we are able to use this file and restore the pending changes.

To instead discard the changes you should open the Data Dictionary and discard the changes with "discardChanges":

>> h = Simulink.data.dictionary.open('myDictionary.sldd')
>> h.discardChanges

Notice that the property HasUnsavedChanges goes from true to false. Please refer to this link for more information:
