function plot_wavelet_quadtree(QT,Theta,j,q,M, plot_type)

% plot_wavelet_quadtree - plot a quadtree at a given wavelet level.
%
%   plot_wavelet_quadtree(QT,Theta,j,q,M, plot_type);
%
%   M is a wavelet transformed image.
%   QT and Theta are computed using the function 
%        [QT,Theta] = compute_wavelet_quadtree(M,Jmin,T,j_min,j_max,s);
