plot3d.m

一种新的时频分析方法的matlab源程序。

% --- PLOT3D plots the 3-dimensional perspective --- %
% of either Hilbert or Wavelet results.                                         %
% Requires the following data file: wvlt,
% which contains the 3-d volume, and axes.
%
% See marked lines in the code to change cases.
