Open the model rtwdemo_roll and represent the Embedded Coder Dictionary by using a coder.Dictionary object. Use this object to access the Storage Classes section of the dictionary, which contains the storage class definitions.

rtwdemo_roll
coderDictionary = coder.dictionary.open('rtwdemo_roll');

Create a coder.dictionary.Section object that represents the Storage Classes section of the Embedded Coder Dictionary.

storageClassesSect = getSection(coderDictionary, 'StorageClasses');

Check if the Storage Classes section contains the example storage class SignalStruct.

exist(storageClassesSect,'SignalStruct')
ans =

  logical

   1

Remove the storage class, and then see whether the definition still exists.

deleteEntry(storageClassesSect,'SignalStruct');
exist(storageClassesSect,'SignalStruct')
ans =

  logical

   0
