function w = patterson_lookup_weights ( n )

%*****************************************************************************80
%
%% PATTERSON_LOOKUP_WEIGHTS sets weights for a Patterson rule.
%
%  Discussion:
%
%    The zeroth rule, of order 1, is the standard Gauss-Legendre rule.
%
%    The first rule, of order 3, is the standard Gauss-Legendre rule.
%
%    The second rule, of order 7, includes the abscissas of the previous
%    rule.
%
%    Each subsequent rule is nested in a similar way.  Rules are available
%    of orders 1, 3, 7, 15, 31, 63, 127, 255 and 511.
%
%    These rules constitute a nested family.  The rules can integrate exactly
%    any polynomial of degree 1, 5, 11, 23, 47, 95, 191, 383 or 767, 
%    respectively.
%
%    The data for N = 511 was supplied by Dirk Laurie, and is derived
%    from a NAG Library function d01arf.

%    Input, integer N, the order of the rule.
%    Legal values are 1, 3, 7, 15, 31, 63, 127, 255 and 511.
%
%    Output, real W(N), the weights of the rule.
%    The weights are positive, symmetric and should sum to 2.
