hilbert-huang transform（HHT）

HHT transform for one-dimensional signal. Contains Empirical mode decomposition (EMD) program. The main function is HHT_Ver02.m.

Example
clc; clear; close all

Ts = 0.0005;
Fs = 1 / Ts;
N = 600;
k = 0 : N-1;
t = k .* Ts;
t = t';
sig(1:300,1) = 6 * sin(100 .* pi .* t(1:300))+0.1;
sig(301:600,1) = 6 * sin(100 .* pi .* t(301:600)) + 1.5 * sin(300 .* pi .* t(301:600))+0.1;
HHT_Ver02(t, sig, Fs);
