How to programmatically comment/uncomment a Simulink block?

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

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

[RAGHUVEER RAJESH]

Yes. there is and I found it out just now after I explored your question :))) in 2015 I was 17 years old and today I am pursuinig my Masters in Engineering.... Wooh!! That was a long time ago!!!... ;-)

Well the answer is: The path value has to be passed as a string. So put the path in ' ' single inverted commas.

Detailed answer with example given below this question.

how to pogrammatically comment and uncomment all the blocks in the simulink model ?

[madhan ravi]

@Akhilesh I am not sure if the following works:

 ModelName = 'my_model.slx'; % here you put the name of your Simulink model
 set_param(ModelName,'Commented','on')
 set_param(ModelName,'Commented','off')

Because in documentation it only mentions about commenting out a block. But even so be the case, you can simply engulf your whole model into a Subsystem and simply comment out that Subsystem block.

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.

Perfect! Thank you, again.

If it's in the docs I couldn't find it...

[Mike Crawford]

To add to this, it can save an additional step by selecting the block and typing "gcb" instead of "gcs".

[Dick Benson]

Excellent. I was lost in the myriad parameters each block / component has.

set_param([gcs,'/L(',num2str(k),')'],'Commented','on')

selects L(k) from the current system and comments it out.

The path value has to be passed as a string. So put the path in ' ' single inverted commas.

For e.g.

set_param('subsystempath','Commented','on')

set_param('subsystempath','Commented','off')

the 'subsystempath' is full path to that subsystem. For e.g. 'modelName/subsystemName...'
