   returns:

      rectan   the array(s) containing the rectangular coordinates of the
               position or set of positions

               [3,n] = size(rectan); double = class(rectan)

               The argument 'rectan' returns in the same units associated
               with 'r'.

               'rectan' returns with the same vectorization measure, N,
                as 'r', 'colat', and 'lon'.
