Return a copy of x with the elements rotated counterclockwise in 90-degree increments. The second argument is optional, and specifies how many 90-degree rotations are to be applied (the default value is 1). The third argument is also optional and defines the plane of the rotation. As such plane is a two element vector containing two different valid dimensions of the matrix. If plane is not given Then the first two non-singleton dimensions are used.
Negative values of n rotate the matrix in a clockwise direction. For example,
rotdim ([1, 2; 3, 4], -1, [1, 2]) 3 1 4 2rotates the given matrix clockwise by 90 degrees. The following are all equivalent statements:
rotdim ([1, 2; 3, 4], -1, [1, 2]) rotdim ([1, 2; 3, 4], 3, [1, 2]) rotdim ([1, 2; 3, 4], 7, [1, 2])
