MATLAB: How to 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.

The difficulty with using the 'PortConnectivity' property of the inport block is that it does not list the port handles to which the inport block's output is connected to, but rather it lists the destination block handles, and port numbers. The easiest way to find out the port information of the destination ports is to use signal line information as below:

%get the porthandles of ports for the inport block
a = get_param('test/In1','PortHandles');          
%get the signal line associated with the output port of the inport
line = get_param(a.Outport,'Line');                  
%get the destination port handles for the signal
dstport = get_param(line, 'Dstporthandle')        
%get the properrites from the handle
port = get(dstport)                                             
%Display the port types of each port
port(1).PortType            
port(2).PortType
