function [index, window] = DetailMeyerWindow(dyadic_points,deg);
% DetailMeyerWindow: Evaluates a bandpass Meyer window
%  Usage:
%    [index, window] = DetailMeyerWindow(L,deg);
%  Inputs: 
%    dyadic-points   Pair of the form 2^j, 2^(j+1)
%    deg    Degree of the polynomial
%  Outputs:
%    index  location of the window on the time axis; contains [2^j 2^(j+1)]
%    window bandpass Meyer window
