hilbtm.m

最新的HHT时频分析程序By Huang and Wu

function hret = hilbtm(IMF)
%this is a new version of hilbt_m. It uses perfect cos waves instead of the
%"copy a chunk of data and flip it" method the previous hilbt_m used. Also,
%instead of just replacing an end section of the original wave with the new wave it uses
%a weight to gradually introduce the new wave. This results in more subler
%jumps of frequency at the joint from the original. Data appears to be "better" in this version after the hilbert
%transform - frequency is smoother, less jitter from the gibs effect.
