## SYNOPSIS

function P = cartprod( varargin )

## DESCRIPTION

```% -*- texinfo -*-
% @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
% @end group
