把HHT和神经网络结合起来，识别出是否故障。对于HHT变换，这里用到的是它的IMF分解，然后用能量理论来判别哪些模组是虚假分量，哪些是是真实分量。对于EMD分解后的谱进行特征提取 ，利用的理论基础就是模糊熵。计算出真实 分量的模糊熵，作为输入层；输出层为两个神经元，为0（故障 ）1（正常 （正常 ）判别该信号是否出现故障。(The combination of HHT and neural network to identify whether the fault. For the HHT transform, here is the use of its IMF decomposition, and then use the energy theory to determine which module is false, which is true component. The theoretical basis for the feature extraction of the spectrum after EMD decomposition is fuzzy entropy. The fuzzy entropy of the real component is calculated, as the input layer, the output layer is two neurons, which is 0 (fault) 1 (normal) to determine whether the signal is faulty.)

此程序的功能是用自相关法求使信号s均方预测误差为最小的预测系数 算法为Levinson-Durbin快速递推算法 (The function of this procedure is signal s with autocorrelation method for the prediction of the minimum mean square prediction error coefficient algorithm for Levinson- Durbin quick recursion method)

自己写的nbcs，但是效果还没有普通BCS方法好，重建采用SL0，自行下载(Write your own nbcs, but the results are not good ordinary BCS method, reconstruction using SL0, to download)

Matlab矩阵大全，里面有各种矩阵，是自己在学Matlab时候总结的，很有用。(Matlab matrix Daquan, which have a variety of matrices, Matlab in school when their own conclusion, and very useful.)
