Function cross #
Calculate the cross product for two vectors in three dimensional space.
The cross product of A = [a1, a2, a3] and B = [b1, b2, b3] is defined
as:
cross(A, B) = [ a2 * b3 - a3 * b2, a3 * b1 - a1 * b3, a1 * b2 - a2 * b1 ]
If one of the input vectors has a dimension greater than 1, the output vector will be a 1x3 (2-dimensional) matrix.
