Unable to save trainingstats in MATLAB 2024a
I am runnning a training script based on a simulink environment. At the end when I try to save the training results, it always throws an error. I am wondering if it has something to do with the .mat format. This issue does not occur in Matlab 2023a.
%% Train the agent
trainingStats = train(agent, env, trainOpts);
%% Save Agent
results_dir = strcat(‘./Results/’,num2str(time(1)),’0′,num2str(time(2)),num2str(time(3)));
mkdir(results_dir)
save(strcat(results_dir,’/TrainingStats.mat’),"trainingStats")
generatePolicyBlock(agent)
save_system(‘untitled’,’Agent’)
%% Simulate
%addpath(‘D:MastersHiWiTikz’)
simEpisodes = 1;
simOpts = rlSimulationOptions("MaxSteps",1250,…
"NumSimulations", simEpisodes);
experience = sim(env,agent,simOpts);
save(strcat(results_dir,’/Experience.mat’),"experience")
The error message is usually:
