小波包分解重构程序，克服小波分解在高频段的频率分辨率较差(Wavelet packet decomposition and reconstruction program, overcome the wavelet decomposition in the poor frequency resolution in high frequency )

第一个是标准差，用于算数学模型均值，评价模型的平均量 第二个熵，用于评价信息量的大小，熵越大信息量越大。 第三个用于pcnn模型,评价是否接近理论模型,残差越小，就越接近理论模型(The first is the standard deviation, the mathematical model is used to calculate the mean, the average amount of uation model. The second entropy, to uate the size of the amount of information, the greater the entropy the greater the amount of information. The third for PCNN model, uation is close to the theoretical model, residual error is smaller, the more close to the theoretical model)
