Syntax

showChanges(entryObj)

Description

showChanges(entryObj) opens the Comparison Tool to show changes made to the data dictionary entry entryObj, a Simulink.data.dictionary.Entry object. The Comparison Tool displays the properties of entryObj as they were when the data dictionary was last saved and as they were when the showChanges function was called.

Represent the data dictionary entry fuelFlow with a Simulink.data.dictionary.Entry object named fuelFlowObj. fuelFlow is defined in the data dictionary myDictionary_ex_API.sldd.

myDictionaryObj = Simulink.data.dictionary.open('myDictionary_ex_API.sldd');
dDataSectObj = getSection(myDictionaryObj,'Design Data');
fuelFlowObj = getEntry(dDataSectObj,'fuelFlow');

Make a change to the entry fuelFlow by assigning it the new value 494.

setValue(fuelFlowObj,494);

Observe the unsaved change to the entry fuelFlow. The Comparison Tool opens and compares side by side the current state of the entry with its most recently saved state.
