Hi,

i would like to run an RLAgent on a Raspberry. Since the RLAgent included in the reinforcement learning toolbox is not supported by code generation it does not seem to be possible to upload that block as itself.

Instead i generated a .mex (matlab executable) file from the trained agent policy (.mat file). See:

https://www.mathworks.com/help/reinforcement-learning/ug/deploy-trained-reinforcement-learning-agents.html.

How can i run the generated .mex file in my simulink model?

Thanks for any tips,

Best regards,

V

You start by programming (or obtaining) an Intel x64 instruction set emulator on your ARM based RRaspberry Pi.

In other words, you do not use .mex* files with Raspberry Pi or Arduino.

Perhaps instead of generating mex (binary) it might be possible to generate C or C++ code.

Yes - see my answer to your other Question, Victor. Your best bet is to bake the agent into Simulink so the code generator regenerates it for the Pi a part of one process. If not, generate the standalone C|C++ code an compile it for the Pi.
