很不错的lmd分析程序，里面有画包络，找纯频，加上自己改进的一些算法-Very good lmd analysis program, which has drawn the envelope, looking for pure frequency, plus some of their own algorithms to improve

针对局部均值分解算法过分解的问题，对程序内部做出了微小的改进，并且程序的运行时间得到了较大缩减(According to the problem of decomposition of local mean decomposition algorithm, small improvements are made to the program, and the running time of the program is greatly reduced.)
