change simulink hierarchy through a script in matlab

To change the hierarchy of a Simulink model through a script in MATLAB, you can use the Simulink API functions. Here's a general approach:

1. First, open the Simulink model you want to modify using the open_system function. For example:

main.m
model = 'myModel';
open_system(model);
39 chars
3 lines

2. Use the add_block function to add new blocks to the model hierarchy. Specify the position and type of the block to add. For example, to add a new Subsystem block at a specific location:

main.m
position = [100, 200, 200, 400]; % [left, top, right, bottom]
add_block('built-in/Subsystem', [model, '/NewSubsystem'], 'Position', position);
143 chars
3 lines

3. Use the move_block function to change the position of existing blocks within the model hierarchy. Specify the path of the block and the new position. For example, to move an existing block called 'BlockA' to a new position:

main.m
blockPath = [model, '/BlockA'];
newPosition = [300, 200, 400, 400]; % [left, top, right, bottom]
move_block(blockPath, newPosition);
133 chars
4 lines

4. After making the necessary changes, save the modified model using the save_system function. For example:

main.m
save_system(model);
20 chars
2 lines

Remember to replace 'myModel' with the actual name of your Simulink model, and adjust other parameters according to your specific requirements.

Please note that depending on your specific needs, you may need to use additional Simulink API functions or modify the example code accordingly. Refer to the Simulink documentation for more detailed information on the available functions and their usage.
