Computes the cartesian product of given column vectors ( row vectors ). The vector elements are assumend to be numbers.
Alternatively the vectors can be specified by as a matrix, by its columns.
To calculate the cartesian product of vectors, P = A x B x C x D ... . Requires A, B, C, D be column vectors. The algorithm is iteratively calcualte the products, ( ( (A x B ) x C ) x D ) x etc.
