Hello,
After you generate the RL environment, i assume you are adding the environment reset function as
env = rlSimulinkEnv(...)
env.ResetFcn = @(in) myResetFunction(in, otherInputs)
Inside of your myResetFunction.m, you can generate your desired matrix at the start of each episode, and then it needs to be added to the Simulink workspace. I found this to be important especially when randomizing parameters in the environment at the start of each episode.
To do this, inside of your myResetFunction use:
function in = myResetFunction(in, otherInputs)
% Here run the function to generate your matrix
NewMatrix = GenerateMatrix(otherInputs) ;
% Then, add this matrix to your Simulink workspace
in = setVariable( in, 'NewMatrix', NewMatrix, 'Workspace', SimulinkModel) ;
% where SimulinkModel is the string containing the name of the Simulink
% model that you are using
end
You should now be able to access the variable NewMatrix inside of Simulink during training, randomized according to GenerateMatrix.m at the start of each episode.
If you wish to randomize other parameters as well, use the exact same procedure, and then add them to the Simulink workspace.
Hope this helps.
