How to read data dictionary and esport to mat file

Hello everyone, I have MATLAB2014a and I am working with data dictionary. I have read online and found following code to read and export data in data dictionary to mat file.

myDictionaryObj = Simulink.data.dictionary.open('Globaldata.sldd');

dDataSectObj = getSection(myDictionaryObj,'Design Data');

exportToFile(dDataSectObj,'myDictionaryDesignData.mat')

When I execute the first command

myDictionaryObj = Simulink.data.dictionary.open('myDictionary_ex_API.sldd');

I get the error that Simulink function or class unknown error.

I have the data dictionary file in my working directory. Can someone help resolving the issue?

The Simulink Data Dictionary API was officially released after R2014a, and the code sample you have is from the R2015a release.

The code for 14a will look like:

myDictionary = Simulink.dd.open('GlobalData.sldd');

This API is undocumented, but this has been covered in other blogs: http://undocumentedmatlab.com/blog/simulink-data-dictionary
