% remember to add the utility functions in ./util/ 
cd code    
matlab generate_ground_truth        % generate ground truth files
matlab main        % generate features and results, function generate_demo_real_trail() in line 110 will generate the real traces, its ground truth, locations of WiFi transmitter and receiver.
