排列熵与多尺度排列熵计算，源于matlab exchange-used for calculating permutation entropy and multiscale PE，which is from Matlab file exchange

常见的熵值计算的matlab 程序统计 样本熵 模糊熵 排列熵 多尺度熵 层次熵等(SampleEntorpy FuzzyEntropy PermutationEntropy HierarchicalEntropy)

对传递熵算法进行改进，引入相位空间重构，对脑电信号进行分析(The transfer entropy algorithm is improved and phase space reconstruction is introduced to analyze EEG signals)

时移多尺度排列熵一种应用于非线性非平稳信号的特征提取方法，能够有效的处理信号特征信息。(Time-lapse multiscale permutation entropy is a feature extraction method applied to non-linear non-stationary signals, which can effectively process signal feature information.)

多尺度样本熵程序，实例中用于一段轴承故障数据，简单易懂。MultiscalePermutationEntropy函数中的PermutationEntropy也可以单独拎出来计算单个样本熵。(The multi-scale sample entropy program, which is used for a section of bearing fault data in an example, is simple and easy to understand. The permutatione
