Hi,

I have created a sample model with the following code

pos_outport = [250 0 282 14];
pos_term = [50 15 75 30];
sys = 'mySys';
new_system(sys); % Create the model
open_system(sys); % Open the model
add_block('Simulink/Commonly Used Blocks/Out1', [sys '/Input1'],'Position', pos_outport);
add_block('Simulink/Commonly Used Blocks/Ground', [sys '/Ground1'],'Position', pos_term);
signal_line = add_line(sys, 'Ground1/1', 'Input1/1', 'autorouting', 'on');
set_param(signal_line, 'Name', 'OutputSignal1');

Now, my question would be which parameter to use in order to set the "Signal must resolve to Simulink signal object" checkbox on the OutputSignal1 signal? I guess it's a set_param call but which parameter name should be used in this case?

Many thanks in advance!

在 MATLAB Online 中打开

srcPort = get_param(signal_line, 'SrcPortHandle');
set(srcPort,'MustResolveToSignalObject', 'on');

Thank you! In the meantime I also received an answer from Support. They additionally told me about set(signal_line,'MustResolveToSignalObject',1) which is also working.
