Matlab Simulink how to select elements by matlab script

Hello,

for code testing, I'd like to select elements of a matlab simulink model by matlab code.

I'd expect to get the (line) handle of the selected simulink item returned AFTER selecting the elements by script.

% * code to select constant1 block * 
handle_of_constant1 = find_system(bdroot,'FindAll','on','Selected','on');

Thank you in advance!

Hi @Steve Oswald,

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);
