rot3d90(A, X, K)

Rotate 3D array over 90 degrees in a particular plane

rot3d90 - rotate 3D array 90 degrees around a specific axis

B = rot3D90(A, X) is the 90 degree counterclockwise rotation of the 3D
array A along a specific axis. X denotes the plane of rotation,
according to the table below. For instance, when X is 1 the plane of
rotation is formed by the 2nd and 3rd dimension.

rot3d90(A, X, K) is the K*90 degree rotation of A, K = +-1,+-2,...

If A has a dimension of [N, M, L], the dimensions of the rotation
depend on X. For value of X, the subindex in the X-th dimension will be
unaffected. Therefore, specific vectors will be unaffected.
Note that rot3d90(A,3) and rot90(A) produce the same result.

X Rotation plane Dimension of B Unaffected vectors
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
1 dims 2 & 3 [N, L, M] N-by-1 (row)
2 dims 1 & 3 [L, M, N] 1-by-N (column)
3 dims 1 & 2 [M, N, L] 1-by-1-by-N (plane)

Example:
A = cat(3,[1 2 ; 3 4],[5 6 ; 7 8])
B = rot3d90(A, 2) % rotation in plane formed by 1st and 3rd dimension
% B(:,:,1) = 5 6
% 1 2
% B(:,:,2) = 7 8
% 3 4
