Simulink: Obtaining propagated signal names programmatically

Hi, I am trying to obtain the propagated signal name for a signal programmatically. For example:

porthandles = get(gcbh, 'PortHandles');
linehandle = get(porthandles.Outport(1), 'Line');

%Assume that the SignalPropagation property is turned off
%As soon as the command below is executed, the name '<PropagatedName>' appears
%on the line in the Simulink model
set(linehandle, 'SignalPropagation', 'all');

Now, is there a property associated with linehandle that lets us obtain this propagated signal name? The 'Name' property returns an empty string.

Thanks.

get(porthandles.Outport(1),'PropagatedSignals')

Can we check whether the propogation is above the line or below the line?

This worked for me:

porthandles = get(gcbh, 'PortHandles');

for ip = 1:numel(porthandles.Inport)

linehandle = get(porthandles.Inport(ip), 'Line');

srchandle = get(linehandle,'SrcPortHandle');

disp(get(srchandle,'PropagatedSignals'));

end

Hi Lukas,

Is it possible to change the propagated signal. if yes, please tell me the way(programmatically).

The signal label is "propagated" so can't be modified at downstream. If you want to change the signal label, change it at its source or simply name it something else directly.
