I understand that you have trained an agent using the PPO algorithm in Julia and would like to transfer the trained neural network weights to MATLAB for testing with a Simulink-controlled engine. While MATLAB does not support direct import of models from Julia, here is a workaround you can follow:
You can manually reproduce the same neural network architecture in MATLAB and then use the "setwb" function to assign the weights and biases. The "setwb" function in MATLAB accepts a neural network object and a single vector containing all weights and biases, allowing you to set them manually.
For more information on the "setwb" function you can refer to the following MathWorks documentation:
Hope this helps!
