How can I get the names and properties of multiple subsystems?

Hello

I would like to get the names of the Subsystems in Simulink and the descriptions of their properties.

Check this out.

% Open model
modelName = 'myModel';
load_system(modelName);

% Find all subsystems in the model
subsystems = find_system(modelName, 'BlockType', 'SubSystem');

% print all the name of subsystems
for i = 1:length(subsystems)
    subsystemName = get_param(subsystems{i}, 'Name');
    fprintf('Subsystem %d: %s\n', i, subsystemName);
end

Subsystem 1: A_Fnc
Subsystem 2: B_Fnc
Subsystem 3: C_Fnc

% To get model description
modelDescription = get_param(modelName, 'Description');

% print out the model's description
fprintf('Model Description: %s\n', modelDescription);

Model Description: Hello !!

Thank you so much.

You're my hero again.

Hey JinWook,

You can use the find_systemfunction to find a specific block, in this case, all the subsystem blocks. Once you have them, you can use the get_param function to get the descriptions of each block iterating over all subsystems you have.

Consider the attached example model called ‘testModel’ that has 3 subsystems and their descriptions. The following code gets all the subsystems and iteratively, all of their descriptions:

% Your Simulink model name
modelName = 'testModel';

% Load the model if its not already open
load_system(modelName);

% Finding all subsystems of the model
subsystems = find_system(modelName, 'BlockType', 'SubSystem');

for i=1:length(subsystems)
    % all the description's of the model
    description = get_param(subsystems{i}, 'Description');
    fprintf('Subsystem Name: %s\n', subsystems{i});
    fprintf('Subsystem Description: %s\n', description);
end

Subsystem Name: testModel/Subsystem1

Subsystem Description: Description1

Subsystem Name: testModel/Subsystem2

Subsystem Description: Description2

Subsystem Name: testModel/Subsystem3

Subsystem Description: Description3
