function [ rexp, sexp ] = poly_ql ( )

%*****************************************************************************80
%
%% poly_ql() returns the monomials for a quadratic/linear quadrilateral.
%
%  Reference Element QL:
%
%    |
%    1  4---5---6
%    |  |       |
%    |  |       |
%    S  |       |
%    |  |       |
%    |  |       |
%    0  1---2---3
%    |
%    +--0---R---1-->
%
%  Formula:
%
%    Given coefficients A(I), the polynomial interpolant at (R,S) is
%
%      P(R,S) = sum ( 1 <= I <= N ) A(I) * R**REXP(I) * S**SEXP(I)
