To Expand Subsystem by using model explorer

Step-2: Apply Simulink.BlockDiagram.expandSubsystem(blockname). This type of Subsystem expansion applies to the currently selected subsystem level. Simulink does not expand other subsystems in a nested subsystem hierarchy which is the functionality you are looking for.

Example:

blocks = find_system(model_name,'Type','Block');
for i = 1:numel(blocks)
    try
        Simulink.BlockDiagram.expandSubsystem(blocks{i})
    catch
        %This will catch when we try to expand anything apart from Subsystem.
        continue
    end
end

Hope it helps.

Hi Sai,

thank you for your solution.

If I try to write below code in Matlab Command window, then I get always this message:

E.g.:

Simulink.BlockDiagram.expandSubsystem('SubsystemExpansionModel/Subsystem')

Invalid Simulink object specifier

Note: subsystems are not masked, linked, or commented.

Thanks

Mustafa

Hi Sai,

thank you for your tip, it has worked.

I have an additional question to top script, what you did write.

I would like to below 'for loop' for certain paths in my model.

E.g.

for i=11:10:1141    
target= find_system ('modelname/subsystemhighestlevel{i}/subsubsystem');
Simulink.BlockDiagram.expandSubsystem('target','CreateArea','Off');
end

Unfortunately it does not work.

Do you know how a path / directory can be counted up iteratively?

Thanks

Mustafa

Hi Sai,

I have solved this issue with below code script based on your first suggestion.

By the way , it is possible to get child subsystem of subsystem on the highest level with 'SearchDepth'......

Thanks and BR

Mustafa

blocks=find_system('model_name','SearchDepth','2','Name','target_subsystem');
for i = 1:numel(blocks)
    try
        Simulink.BlockDiagram.expandSubsystem(blocks{i})
    catch
        %This will catch when we try to expand anything apart from Subsystem.
        continue
    end
end
