ROT90

 

 Rotate matrix 90 degrees.

  rot90(A) is the 90 degree rotation of m x n matrix A.

  rot90(A,k) is the k*90 degree rotation of A, k = +-1,+-2,...

  For example,

 

 

        A = [1 2 3      B = rot90(A) = [ 3 6

             4 5 6 ]                     2 5

                                         1 4 ]

 

 

  mesh(B) then shows a 90 degree counter-clockwise rotation

  of mesh(A).
