function plotquadtfdist(p, varargin);
%PLOTQUADTFDIST Plot quadratic time-frequency distribution
% Usage: plotquadtfdist(p);
%
% 'plotquadtfdist(p)' plots the quadratic time-frequency distribution
% on the time-frequency plane. The quadratic time-frequency distribution
% should be a square matrix.
%
% PLOTQUADTFDIST takes the following additional arguments:
%
% 'dynrange',r
% Limit the dynamical range to r by using a colormap in
% the interval [chigh-r,chigh], where chigh is the highest
% value in the plot. The default value of [] means to not
% limit the dynamical range.
%
% 'db' Apply 20*log_{10} to the coefficients. This makes
% it possible to see very weak phenomena, but it might show
% too much noise. A logarithmic scale is more adapted to
% perception of sound. This is the default.
%
% 'dbsq' Apply 10*log_{10} to the coefficients. Same as the
% 'db' option, but assume that the input is already squared.
%
% 'lin' Show the coefficients on a linear scale. This will
% display the raw input without any modifications. Only works for
% real-valued input.
%
% 'linsq' Show the square of the coefficients on a linear scale.
%
% 'linabs' Show the absolute value of the coefficients on a linear scale.
%
% 'tc' Time centring. Move the beginning of the signal to the
% middle of the plot.
%
% 'clim',clim Use a colormap ranging from clim(1) to clim(2). These
% values are passed to imagesc. See the help on imagesc.
%
% 'image' Use imagesc to display the plot. This is the default.
%
% 'contour' Do a contour plot.
%
% 'surf' Do a surf plot.
%
% 'colorbar' Display the colorbar. This is the default.
%
% 'nocolorbar' Do not display the colorbar.
%
% 'display' Display the figure. This is the default.
