中文说明：EMD与EEMD实现代码，可以用于IMF分解，得到不同IMF之后，本人专业为机械故障诊断学，用于分析机械故障信号，可选取相应的IMF分量做FFt或者其他包络解调方法，来找寻故障信息
English Description：
EMD and EEMD implementation code, can be used for IMF decomposition, get different IMF, I professional for mechanical fault diagnosis, for the analysis of mechanical fault signal, can select the corresponding IMF component to do FFT or other envelope demodulation method, to find fault information
