% @deftypefn {Function File} {} cartprod (@var{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.
%
% @example
% @group
% 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
