说明：  我发现这个代码的Java版本：https://galweejit.wordpress.com/2010/12/16/ai-class-implementation-of-mdp-grid-world-from-week-5-unit-9/ 我把它给coverted Matlab代码，我和图示做到了。 该代码只接受一个障碍“汇”的价值。 你可以改变终端，障碍和启动位置。
( I found the java version of this code in:https://galweejit.wordpress.com/2010/12/16/ai-class-implementation-of-mdp-grid-world-from-week-5-unit-9/ I coverted it to Matlab code and I made it with graphical representation. The code accepts only one obstacle sink value. You can change terminals, obstacle and start positions.)
