it is an ebook to know different methods of recovering your hard disk.

一本非常有价值的MAtlab编程参考书，值得一看。(A very valuable reference book MAtlab programming, worth a visit.)

说明：  一些制作正交曲线网格的matlab源程序(produced some curves orthogonal grid Matlab source)

STC波形处理方法，提取波列慢度，应用于地震资料处理与测井资料处理中(STC waveform processing method to extract wave train slow degrees, applied to seismic data processing and logging data processing)

AHP层次分析法计算判断矩阵的最大特征值,是学习PCA特征提取的很好的学习资料，STM32制作的MP3的全部资料。( Calculate the maximum eigenvalue judgment matrix of AHP, Is a good learning materials to learn PCA feature extraction, STM32 all the information produced by the MP3.)

说明：  bP网络,网络的训练算法是反向传播算法，即神经元的链接权重的训练是从最后一层(BP network, network training algorithm is BP back propagation algorithm, i.e., neurons in the link weight training is from the last layer)

说明：  信号预处理，提取PCG特征，利用机器学习进行分类（含数据）(Signal preprocessing, PCG feature extraction, machine learning for classification (including data))

用matlab来演奏张信哲的《过火》，比较有意思的一个程序(Matlab to play Jeff Chang' s " gone too far" , one of the more interesting program)

说明：  运用多重网格求解泊松方程和双曲线方程，大家下着用吧 很好的 哈哈(use the multigrid method to solve posion equation)
