Access block output data from simulink in python

Hi All,

I am trying to run a simulink model form python using matlab engine. I am able to load the model and data in the workspace and run the simulation. I would like to read the outputs of a subsytem block from the simulink model during simulation that I can then use in python.

I tried using the add_exec_event_listener function in the startFcn callback of the subsystem

blk = 'path/to/the/subsystem'
add_exec_event_listener(blk,'PostOutputs',@readsubsysdata)

where readsubsysdata.m is

function [data1] = readsubsysdata(block,~)
data1 = block.outport(1).data;
end

How do I read the data from the block in python during the simulation? I am not sure if I completely follow the steps of doing so.

Thanks in advance!
