function [ g, c, h ] = constants ( )

%*****************************************************************************80
%
%% constants() stores, and returns constants "g", "c" and "h".
%
%  Discussion:
%
%    Calling [g,c,h]=constants() returns the values of g, c, and h.
%
%    Because the values never change, and don't need to be computed,
%    we use assignment statements here, instead of persistent data.
