How to export simulink data to workspace during simulation?

Question

I want to retrieve the data from simulink during simulation, and use serial network function to send these data to another program. Because I need to use an

Answer 1

Use get_param to read data from just at the current time. Also to send the data back to Simulink with set_param of a gain or another block.

An example of get_param

First load and start the simulation:

load_system('myModel')
set_param('myModel','SimulationCommand','Start');

To read data on any line of your simulink model:

1. Get a simulink block object (let's try a Clock with the name Clock):

   block = 'myModel/Clock';
   rto = get_param(block, 'RuntimeObject');
   

2. Then get the data on its first (or any) output port (or input) of that block.

   time = rto.OutputPort(1).Data;
   

You could do the reading, in a timer callback.
