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')

storageClassesSect = 

  Section with properties:

    Name: 'StorageClasses'

Get a list of the storage class definitions in the section. Use the find method to get the coder.dictionary.Entry objects in the section. Then, use the get method to list the names of the definitions that the entries represent.

entryObjects = find(coderDictionary, 'StorageClasses');
get(entryObjects,'Name')

ans =

  1×19 cell array

  Columns 1 through 4

    {'ExportedGlobal'}    {'ImportedExtern'}    {'ImportedExternP…'}    {'BitField'}

  Columns 5 through 9

    {'Const'}    {'Volatile'}    {'ConstVolatile'}    {'Define'}    {'ImportedDefine'}

  Columns 10 through 13

    {'ExportToFile'}    {'ImportFromFile'}    {'FileScope'}    {'Localizable'}

  Columns 14 through 18

    {'Struct'}    {'GetSet'}    {'CompilerFlag'}    {'Reusable'}    {'SignalStruct'}

  Column 19

    {'ParamStruct'}

Remove the example storage class ParamStruct from the dictionary.

deleteEntry(storageClassesSect,'ParamStruct');
