plotframe(F,c,…); C = plotframe(...);
plotframe(F,c) plots the frame coefficients c using the plot command associated to the frame F.
C=plotframe(...) for frames with time-frequency plots returns the processed image data used in the plotting. The function produces an error for frames which does not have a time-frequency plot.
plotframe(F,c,...) passes any additional parameters to the native plot routine. Please see the help on the specific plot routine for a complete description.
The following common set of parameters are supported by all plotting routines:
| 'dynrange',r | Limit the dynamical range to r. The default value of [] means to not limit the dynamical range. |
| 'db' | Apply \(20\cdot \log_{10}\) 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 \(10\cdot \log_{10}\) 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. |
| 'clim',clim | Only show values in between \(clim(1)\) and \(clim(2)\). This is usually done by adjusting the colormap. See the help on imagesc. |
