How do I query the data type of every input and output port in a Simulink model?

When I select Port data types from the Format menu of a Simulink model, I can see the data type of every input and output port in this model. I would like to query these data types from command line or a script, and I also want to be able to do this using a generic model name such as gcs.

Note that in order to query the data type, you need to compile the model first. Try the following example:

vdp

% open the model                    

vdp([],[],[],'compile'); 

% compile the model

h = get_param('vdp/Mu','Porthandles');

% get the port handles

get_param(h.Outport,'CompiledPortDataType')

% get the output port data type

vdp([],[],[],'term')  

% terminate the compilation

For a generic model name such as 'gcs', consider using the EVAL function. Here is an example:

vdp

eval([gcs,'([],[],[],''compile'');'])

h = get_param('vdp/Mu','Porthandles');

get_param(h.Outport,'CompiledPortDataType')

eval([gcs,'([],[],[],''term'')'])
