How to use add_block function to add a new block into the subsystem?

i just create a new Library which called Steuergeraet in Simulink.In this Libray there is two block, SG1(Subsytem) and DC_DC.

Here is the code, with which I want to add the Block DC_DC into SG1.

add_block('Steuergeraet/SG1',[gcs,'/SG1'],...
    'Position', [140 50 270 125]);
set_param(gcb, 'LinkStatus', 'inactive');
add_block('Steuergeraet/DC_DC','/SG1/DC_DC','MakeNameUnique','on');

But there is error in third line.

A new block named '/SG1/DC_DC' cannot be added

Really aprreciate, someone can give some suggestion.!

Regards.

Perhaps you need to unlock the libaray?

set_param('library_name', 'Lock', 'off');

I can't test it right now, but library_name might be 'Steuergeraet', or perhaps 'Steuergeraet/DC_DC'?

[wang]

set_param(gcb, 'LinkStatus', 'inactive');

this command was used to disable the libray link.otherwise can not put or change the block in the subsystem.
