How can I find the names of the ports within a subsystem that an external block is connected to in Simulink through the MATLAB command line?

I have a model consisting of subsystems and library blocks. I have a block "Block1" connected to a subsystem "Subsystem1". I would like to know which port within "Subsystem1" is connected to the "Block1" input port through the MATLAB command line.

There is no straightforward way to determine which port within a subsystem an input port or output port of an external block is connected to and what its name is.

The attached "dispconn.m" script file demonstrates how you can determine the ports connected at the input and output of the 'Actuator Model' block in the 'f14' demo model.

You need to make use of similar logic to determine the names of ports within blocks that are connected to any block in your model.
