How can I comment out Simulink subsystem from Matlab script?

Hi,

I just found out that there is a great option in Simulink which allows to comment out blocks and subsystems and exclude them form simulaton (right-click on block -> Comment out). I'd like to know, how can I do that using Matlab sctipt (or is it even possible?).

Thanks, Krzysztof

Suppose your model name is untitled , and you want to comment out the block named Unit Delay

set_param('untitled/Unit Delay','commented','on')

% to uncomment

set_param('untitled/Unit Delay','commented','off')

Wow, that was fast! Thanks!

Can this command be applied to a subsystem? I tried it for a subsystem in my model and it didn't work. Any help?

[Azzi Abdelmalek]

This should work for any block.

[Krzysztof Szczupak]

Yes, this is working also for subsystems. Maybe you're providing wrong path for the subsystem? In the model click on the subsystem you want to comment, then in command window type this command:

set_param(gcb,'commented','on')

( gcb returns path to currently highlighted object on the model). This should comment subsystem you've clicked on.

I tried to comment subsystem using above mentioned command but it throws error like invalid object name. I am doing it in 2019b will it support for this version

@Shekhar Lokhare same doubt for me but it is for bus creator and bus selector based one,

here the question

Yes. true, its not working for a subsystem. The command is only applicable for simulink blocks. Has anyone else explore some other solution.
