decomposition
运行emd,得到输入信号X的固有模态函数（imf），每列代表着信号X的一阶分量，X就是我们采集的信号。
hhtdn是hht去噪的程序，可以不看，仅看emd 和 findpeaks
wvtdn是wavelet去噪程序，如果只是分解信号，仅用下面的语句即可
[C,L] = wavedec(x_noise,dl,wn);
x_noise就是我们采集的信号，dl是分解的阶数，wn是分解的母小波名称(% Empiricial Mode Decomposition (Hilbert-Huang Transform)
% imf = emd(x)
% Func : findpeaks)
