function [ a, b ] = p23_lim ( dim_num )

%*****************************************************************************80
%
%% P23_LIM returns the integration limits for problem 23.
%
%  Discussion:
%
%    Because the integration region is the interior of the unit simplex,
%    the integration limits simply specify the limits of a box containing 
%    the integration region.
