How to get the callbacks of the Simulink model?

I am trying to get the callbacks of a particular model of simulink using matlab programming, i am new to simulink and can you help me what function can i use to get the callbacks present?

Hi!

To get the callbacks of a particular model in Simulink using MATLAB programming, you can use the find_mdlrefs function. This function allows you to search for all Model Reference blocks in a given model and then obtain the callbacks associated with those blocks.

Here is the snippet of code that you can refer:

modelName = 'YourModelName';  % Replace 'YourModelName' with the name of your Simulink model
load_system(modelName);
refs = find_mdlrefs(modelName);
callbacks = cell(0);
for i = 1:numel(refs)
    blockPath = refs{i}.Block;
    callbackData = get_param(blockPath, 'Callbacks');
    callbacks{end+1} = callbackData;
end

Now, the callbacks cell array will contain the callback information for each Model Reference block present in your model. Each cell entry will be a structure containing information about the callbacks for that specific block.

You can also use get_param to get the model callbacks.

You can refer to the get_param and mdlrefs documentation and use according to your use case. I hope this helps!

Hi Robert,

To obtain the callbacks of a particular model in Simulink using MATLAB, you can use the "find_system" function along with the Callbacks option. Here's an example:

% Specify the name of your Simulink model
model_name = 'your_model_name';

% Find the callbacks in the Simulink model
callbacks = find_system(model_name, 'LookUnderMasks', 'all', 'FollowLinks', 'on', 'BlockType', 'SubSystem', 'Callbacks', 'all');

In this example, replace 'your_model_name'`with the actual name of your Simulink model. The "find_system" function is used to search for blocks in the model that have callbacks. The `'LookUnderMasks', 'all'` option is used to search for callbacks within masked subsystems, and `'FollowLinks', 'on'` ensures that the search includes linked subsystems. The `'BlockType', 'SubSystem'` option narrows the search to subsystem blocks, and `'Callbacks', 'all'` specifies that all types of callbacks should be included in the search.

After executing this code, the `callbacks` variable will contain a cell array of the callbacks present in the specified Simulink model.

Note that this approach will find callbacks within subsystems, but not at the top-level of the model or within individual blocks. If you want to find callbacks in other parts of the model, you can modify the options of the `find_system` function accordingly.
