function node_h = h_coef ( node_num, node_xy )

%*****************************************************************************80
%
%% H_COEF evaluates the coefficient H(X,Y) of DEL U in the Poisson equation.
%
%  Discussion:
%
%    The equation is
%
%      - Del H(X,Y) DEL U + K(X,Y) * U = RHS(X,Y)
