Home MDP Policy Plot for a Maze
 I have a 5x-5 maze specified as follows. r = [1 0 1 1 1 1 1 1 0 1 0 1 0 0 1 1 1 1 0 1 1 0 1 0 1];  Where 1's are the paths and 0's are the walls. Assume I have a function foo(policy_vector, r) that maps the elements of the policy vector to the elements in r. For example 1=UP, 2=Right, 3=Down, 4=Left. The MDP is set up such that the wall states are never realized so policies for those states are ignored in the plot. policy_vector' = [3 2 2 2 3 2 2 1 2 3 1 1 1 2 3 2 1 4 2 3 1 1 1 2 2] symbols' = [v > > > v > > ^ > v ^ ^ ^ > v > ^ < > v ^ ^ ^ > >]  I am trying to display my policy decision for a Markov Decision Process in the context of solving a maze. How would I plot something that looks like this? Matlab is preferable but Python is fine. Even if some body could show me how to make a plot like this I would be able to figure it out from there.
