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. |
