I am coding a small plugin that emulates the behaviour of Hifi Headphones, and i get the following error :

Generating mex file 'testbench_HeadPhoneSimulator_002_mex.mexmaci64'... ??? Size mismatch (size [1 x 13] ~= size [1 x 28]).
    The size to the left is the size of the left-hand side of the assignment.
More information
Error in ==> HeadPhoneSimulator_002 Line: 152 Column: 13
Code generation failed: View Error Report
Error using coder.internal.generateAudioPlugin
Error in validateAudioPlugin

The function that calls the error is the following:

function set.Monitor( plugin , val )
            plugin.Monitor = val;
            updateMonitor(plugin);
end

All that this should do is change which of the available Monitor Headphones are in use and call the "updateMonitor" function, which is used to change the behaviour of the filter that compensate the frequency response of the user's headphones.

I am using the "enum" mapping like this :

audioPluginParameter('Monitor',...
            'DisplayName','Monitor',...
            'Mapping',{'enum','None',...
                              'AKG K240 MKII',...
                              'BeyerDynamic DT990 (250 ohm)',...
                              'BeyerDynamic T1',...
                              'Sennheiser HD600'},...
            'Layout',[1,1]),...
