Hello,
is it possible to trigger the command in Simulink "double left click on line -> rename line" from MATLAB?
The command
set_param(OBJ,'OutputSignalNames','test')
isn't possible, because the parameter is read only (btw. i do not understand why). I'm not able to change the name of the line directly (e.g. with setname, handles...)
To avoid problems during run or compilation time i used the "PreSaveFct" to call the m-file.
I could open the mdl-file as a text file and change the names directly. But this isn't convenient.
thanks for the help!
Carsten

It can be done. You just need to get the handle of the signal line.
There are many ways to get the handle of the signal line. In this example, assume the block has one outport.
PortHandles=get_param(gcb,'PortHandles');
set_param(PortHandles.Outport(1),'Name','NewSignal');
