基础的音频处理matlab程序，设计巴特沃斯低通数字滤波器实现滤波。(Matlab-based audio processing procedures, Butterworth low-pass digital filter designed to achieve the filtering.)

本程序用于基因数据的分类，我自己写了一个基于欧氏距离的费舍尔判据，选取有代表性的基因，最后用NMF将矩阵分解，对得到的矩阵进行分类，分类用的是自带的svm算法(It is used for classfication, I wrote a fisher criterion based on Euclidean distance, selecting representative genes,after NMF,classification with the SVM algorithm is shipped )

说明：  利用小波分析具有时频局部化特性和熵能对系统状态进行表征的特点，将小波分析和熵结合起来，定义了3种小波熵（小波能谱熵、小波时间熵、小波奇异熵），并给出其算法，揭示了这3种小波熵对系统故障表征的机理，对两种理论信号和基于PSCAD/EMTDC仿真的输电线路故障信号(Based on the characteristics of time-frequency localization of wavelet analysis and entropy energy to represent system state, three kinds of wavelet entropy (wavelet energy spectrum entropy, wavelet time entropy and wavelet singular entropy) are defined by combining wavelet analysis and entropy, and their algorithms are given. The mechanism of these three kinds of wavelet entropy for system fault characterization is revealed. The results show that the three kinds of wavelet entropy can be used to characterize system fault Road fault signal)

说明：  用matlab强大的数学算法引擎去实现语音识别，对过去的方法进行综述，并有所创新(Using matlab powerful mathematical algorithms to realize the speech recognition engine, the past methods of synthesis and innovation)

说明：  ANN-BP分类器设计，用其中一半的数据采用ANN-BP算法设计分类器，另一半数据用于测试分类器性能。(ANN-BP classifier design, with half of the data using ANN-BP algorithm design classifier, the other half of the data used to test the classifier performance.)

实现阵列信号处理MUSIC算法中对比不同的信噪比对算法的分辨率的影响。(MUSIC realize array signal processing algorithms compare the effects of different signal to noise ratio of the algorithm of resolution.)
