改进型的小波包与PNN的联合故障诊断新方法（improved wavelet packet and PNN）

改进型的节点重构小波包频带能量谱与PNN（概率神经网络）的联合故障诊断新方法。 有具体的数据和程序，经过本人验证的，程序有效！效果很好！

function [we_enegy]=im_wavelet_package（ss）

sjl=ss;
fs=12000;
T=1/fs;
L=length（sjl）;

s=sjl‘;


%下面开始用改进的单子带重构算法进行近似部分的小波分解
cA01=sr_appcoef（sfs1‘db45‘）;
cA1=dyaddown（cA010）;                                                  %尺度1的低频系数
cA021=sr_appcoef（cA1fs2‘db45‘）;
cA21=dyaddown（cA0210）;                                                  %尺度2的低频系数
cA031=sr_appcoef（cA21fs3‘db45‘）;
cA31=dyaddown（cA0310）;                                                  %尺度3的低频系数

%用改进的单子带重构算法进行近似部分的小波重构
ca1=sr_apprec（cA01L1‘db45‘）;                                       %尺度1的低频重构系数
ca21=sr_apprec（cA021L2‘db45‘）;                                        %尺度2的低频重构系数
ca31=sr_apprec（cA031L3‘db45‘）; %（‘31‘）



%用该进的单子带重构算法求细节部分Dj
cD01=sr_detcoef（sfs1‘db45‘）;      %尺度1的高
