PLOTQUADTFDIST - Plot quadratic time-frequency distribution

Usage

plotquadtfdist(p);

Description

'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.
