说明：  EEMD函数的.m文件。对任意格式的数据进行系踪经验模式（EEMD）分解。在语音处理中可以用于通过对不同级数的分解波形中提取基音频率
(EEMD function. M file. Performed on the data system to track any format empirical model (EEMD) decomposition. In speech processing can be used by extracting the pitch frequency of the different stages of decomposition waveform)
