get simulink block subsystem compiledportdimension in matlab

To get the CompiledPortDimensions property of a Simulink Block/Subsystem programmatically via MATLAB, you can make use of the get_param function.

Here's an example code snippet:

main.m
% Define the block/subsystem name
blockName = 'mySubsystem';

% Get the CompiledPortDimensions property of the block
portDimensions = get_param(blockName, 'CompiledPortDimensions');

% Display the port dimensions
display(portDimensions);

In the code above, we first define the name of the block/subsystem whose CompiledPortDimensions property we want to obtain. Then, we use the get_param function to obtain this property value and store it in the portDimensions variable. Finally, we display the portDimensions value using the display function.

Note that when obtaining the CompiledPortDimensions property, the block/subsystem whose port dimensions you want to obtain should already have been compiled at least once. Otherwise, an error may occur.
