MATLAB: How to programmatically comment/uncomment a Simulink block

simulink

Simulink blocks can be commented/uncommented using Ctrl+Shift+X.

Is there a way to do this programmatically in a Matlab script?

Best Answer

Yes, you can do

set_param(blockName,'Commented','on')
set_param(blockName,'Commented','off')

... or if the block has 1 input and 1 output port, you can also comment through

set_param(blockName,'Commented','through')

Here, blockName is the name of the block, which you can obtain by selecting the block and typing gcs.

You can use an annotation to comment and uncomment a block by enterting the code below as the 'ClickFcn' for the annotation.

if(strcmp(get_param(path_to_block,'Commented'),'on'))
    set_param(path_to_block,'Commented','off');
else
    set_param(path_to_block,'Commented','on');
end

Unfortunately, annotation properties can not be accessed programatically and hence, you will not be able to change the color of the annotation based on whether the block is commented or not.

MATLAB: Syntax to comment/uncomment line(s) of code in a Matlab script

There is no way (at least as far as I am aware) to comment out lines programatically. However, even if you could, this is almost certainly not a good approach for what you are trying to do.

Instead, I think the easiest way is just to wrap it in an if statement

if (user_input_condition_1)
    %code to run for case 1
else
    %code to run for case 2
end

You can also use switch statements instead of the if statements--the approach is similar.
