stft谱分解，已经过实际验证，效果很好(stft spectral decomposition, has been actually verified with good results)

基于matlab，可以将数据输出为txt或者为dat格式的程序(Based on matlab, data can be output as a txt or dat format for the program)

匹配追踪工具包（MPTK）提供了快速实现匹配追踪算法的多通道信号的稀疏分解。它包括一个C + +库，独立的命令行实用程序，还有一些脚本运行它，并通过Matlab的绘图结果。(The Matching Pursuit Tool Kit (MPTK) provides a fast implementation of the Matching Pursuit algorithm for the sparse decomposition of multichannel signals. It comprises a C++ library, standalone command line utilities, and some scripts for running it and plotting the results through Matlab.)

用于分类的主判别变量算法(principal discriminant variate algorithm) ( principal discriminant variate algorithm for two classes, x1 and x2. x1 is the training samples in the 1st class with each column being the spectrum characterizing the corresponding sample. x2 is the training samples in the 2nd class with each column being the spectrum characterizing the corresponding sample. lamda is the penalty weight defining the balance between FLDA and PCA. dvnum is the number of principal discriminant variates to be computed. A defaul value for dvnum is 2. dv is the principal discriminant variates. scores is the matrix with each row being the scores of the samples on the corresponding principal discriminant variate. xmean is the mean spectra of the sample, which was used for mean-centering the data in training and prediction. )
