Function File: cartprod (varargin)

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.

  cartprod(1:2,3:4,0:1)
  ans =   1   3   0
          2   3   0
          1   4   0
          2   4   0
          1   3   1
          2   3   1
          1   4   1
          2   4   1
