Problem 54035. Matrix Rotation

There are several errors in the "correct" values for the tests. For example, text #13 has a capital P replaced with a lower case p. Test 11 seems to have an iincorrect value for n. There are also errors in tests 5, 6 and 8.

I'm getting different answers for tests 5, 6, 8, 11, and 13.

In test 6 the center point should not change; in test 8 the center 3 by 3 should not change; test 11 would be ok if n=2,6,10,....

I agree with Tim's comments on tests 6 and 8. I would sum things up by saying that the correct results for tests 6, 8, 11 and 12 are:
Problem 6:
y = [2 1 2 1 2; 1 2 1 2 1; 2 1 1 1 2; 1 2 1 2 1; 2 1 2 1 2];
Problem 8:
y = [0 0 0 0 1; 0 1 0 0 0; 0 0 1 0 0; 0 0 0 1 0; 1 0 0 0 0];
Problem 11:
y = [2 1 2 1 2 1 2; 1 4 5 4 3 4 1; 2 3 2 1 2 5 2; 1 4 1 1 1 4 1; 2 5 2 1 2 3 2; 1 4 3 4 5 4 1; 2 1 2 1 2 1 2];
Problem 12:
y = [13 14 15 16; 9 10 11 12; 5 6 7 8; 1 2 3 4];

I hate to say it, but tests 8 and 12 still seem to be incorrect.
