Simulink blocks can be commented/uncommented using Ctrl+Shift+X.
Is there a way to do this programmatically in a Matlab script?

@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.

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

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...'
If it helps, please let me know...
