What is "the dictionary"? How are you trying to store it? What error message are you getting?

Does it have anything to do with Simulink Data Dictionaries as suggested in http://uk.mathworks.com/matlabcentral/answers/231420-how-to-save-dictionary-to-a-mat-file#answer_187460 ?

Dictionary means data stored in .mat format. my code is as follows

save ('dict.mat', D);

But when it is load into another file, like

load dict.mat;

it shows dict.mat is not loaded
