MATLAB: Tell what type of line is selected in Simulink

buslinesimulinktype

Is there any way that I can tell what a line is from the coommand line. I would like to see if a line is a bus or just a normal line without looking at the model.

There is a parameter called SignalHierarchy which gives information about bus signals, but it is available on port handles, not line handles. You can try something like the following to obtain the information via a line handle:

>> get_param(get_param(lineHandle, 'SrcPortHandle'), 'SignalHierarchy')

The BusObject and Children fields should be non-empty for buses.

MATLAB: How to obtain the port types of destination ports connected an output port of any Simulink block, from the command line

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
