I see you want to select elements of your Simulink model progammatically and obtain their handles. To do so you can use the “find_system” function. Here is an example on how you can do it:
1.) Open your Simulink model and use the “set_param” function to select the block. Make sure you know the full path of the block within the model.
2.) Then use the “find_system” to get the handle of the selected block.
Here is an example code to help you:
% Open the Simulink model
open_system('your_model_name'); % Replace with your actual model name
% Define the block path
blockPath = 'your_model_name/Constant1'; % Replace with the actual block path
% Select the block programmatically
set_param(blockPath, 'Selected', 'on');
% Retrieve the handle of the selected block
handle_of_constant1 = find_system(bdroot, 'FindAll', 'on', 'Selected', 'on');
% Display the handle
disp(handle_of_constant1);
