navigate simulink levels from script in matlab

To navigate Simulink levels from a script in MATLAB, you can use the Simulink API functions.

First, you need to load the Simulink model using the load_system() function.

main.m
model_name = 'your_model_name'; % Replace with your Simulink model name
load_system(model_name);

3 lines

After loading the model, you can get the root level of the Simulink model using the get_param() function with the 'Object' option.

main.m
root_level = get_param(model_name, 'Object');

From the root level, you can access the child levels using the find() function with the 'SearchDepth' option to specify the level depth you want to search. For example, to access all the blocks in the root level, you can use the following code:

main.m
blocks = find(root_level, 'SearchDepth', 1, 'BlockType', 'Block');

2 lines

You can loop through the blocks and access their parameters or manipulate them as needed. To navigate to the next level, you can use the find() function again with the next level as the starting point.

Here is an example to iterate through all blocks in the root level and their sublevels:

main.m
% Load the Simulink model
model_name = 'your_model_name';
load_system(model_name);

% Get the root level
root_level = get_param(model_name, 'Object');

% Get all blocks in the root level
blocks = find(root_level, 'SearchDepth', 1, 'BlockType', 'Block');

% Loop through the blocks and navigate to sublevels
for i = 1:length(blocks)
    block = blocks(i);
    
    % Access block parameters or perform operations
    disp(get_param(block, 'Name'));
    
    % Get sublevels of the current block
    sublevels = find(block, 'SearchDepth', 1, 'BlockType', 'Block');
    
    % Loop through the sublevels and access their parameters
    for j = 1:length(sublevels)
        sublevel_block = sublevels(j);
        
        % Access sublevel block parameters or perform operations
        disp(get_param(sublevel_block, 'Name'));
    end
end

Remember to replace 'your_model_name' with the actual name of your Simulink model.
