MATLAB: How to programmatically replace a referenced model with a Subsystem in Simulink

Question

I have a Simulink model with a model reference. I would like to programmatically replace the 'Model' block with a 'Subsystem' block.

Answer 1

Assuming that you have a 'parent.slx' model which references a model 'child.slx' (whose block name is 'Model' in the parent Simulink model), use either of the following options:

1)

>> open_system('parent');

>> add_block('built-in/Subsystem',['parent/mySub']);

>> load_system('child');

>> Simulink.BlockDiagram.copyContentsToSubsystem('child',['parent/mySub']);

>> pos = get_param('parent/Model','position');

>> delete_block('parent/Model');

>> set_param('parent/mySub','position',pos);

2)

>> open_system('parent');

>> load_system('child');

>> convert2subsys('child');

>> add_block('child/Subsystem','parent/mySub');

>> pos = get_param('parent/Model','position');

>> delete_block('parent/Model');

>> set_param('parent/mySub','position',pos);

>> close_system('child',0);

where 'convert2subsys' is defined at the following link:
