Hi,

I want to set a model callback function with Input Argument(a cell) and return value(cells). Actually I want to register Listeners of all nonvirtual blocks to get the execution order in a period of time. So I decided to use 'StartFcn' to call a function to Register it. I found that the value of 'StartFcn' can only be {''}. Are there anyways to pass the Argument in the callback function and get the return value back? What I want is just like:

set_param(model_name,'StartFcn','execution_order = callback_function(non_virtual_blocks)');

I have thought to set Metadata to store the Input Atgument, but I can't get modelname in the Callback function. Here is the link. https://de.mathworks.com/help/simulink/slref/simulink.mdlinfo.getmetadata.html

Here is a relativ question i found in Mathworks, maybe can inspire you to find some way to help me. https://de.mathworks.com/matlabcentral/answers/87676-return-value-from-timer-callback-function https://de.mathworks.com/matlabcentral/answers/19135-set_param-and-callback-argument
