Their is a command for this already built in. rot90(x)

Test	Status	Code Input and Output
1	Pass	x = [1 2;3 4]; y_correct = [2 4;1 3]; assert(isequal(rotMatrix(x),y_correct))
2	Pass	x = [1 2 3;4 5 6;7 8 9]; y_correct = [3 6 9;2 5 8;1 4 7]; assert(isequal(rotMatrix(x),y_correct))
3	Pass	x=[1 2 3 4 5;6 7 8 9 0] y_correct = [5 0;4 9;3 8;2 7;1 6]; assert(isequal(rotMatrix(x),y_correct)) x = 1 2 3 4 5 6 7 8 9 0
