Number of input/output ports with widths for S-function

Question

Given a process model in a C S-function (or a .mexw file), how can one determine the number of input/output ports together with their port widths programatically in Matlab (in a .m script file) without hardcoding them?

You can use the same technique as in How can I get signal dimensions in Simulink model for the port widths. I believe the CompiledPortDimensions property should give you the number of I/O ports. You'll need to compile the model first though.

What about finding number of ports and widths for a block from the block diagram library? – remus Nov 25 '13 at 09:51
The same applies I believe – am304 Nov 25 '13 at 09:53
