代码说明:

  经验模态分解方法简称EMD方法。该方法从本质上讲是对一个信号进行平稳化处理,其结果是将信号中真实存在的不同尺度波动或趋势逐级分解开来,产生一系列具有不同特征尺度的数据序列。(Empirical mode decomposition method is referred to as the EMD method. This method is in essence a signal smoothing processing, the result is the real signal different scales swings or trends gradual decomposition open, resulting in a series of a data sequence having a different characteristic scale.)
