本代码是超变异模式识别的代码，能通过输入多个模式来进行识别分类。(The code is super-variant pattern recognition code, through the importation of a number of models to identify the classification.)

说明：  cancorr的matlab程序。用于信号的典型相关分析。(The matlab program cancorr. For the canonical correlation analysis.)

主要介绍matlab中simulink的使用情况，里面图标的介绍以及如何画出模块图(Matlab simulink introduced in the usage of the icons inside, and how to draw block diagram)

说明：  Wavelet Packet Decomposition details and codes

说明：  各种数码之间的相互转换，比如2进制转10进制(Base Conversion Algorithm)

This method handles the border by repeating the closest values to the point accessed. This is different from matlabs border handling.

Title: "Voice Recognition and Identification system". Mainly involves: 1: Human speaker recognition 2: Technical data of samples 3: linear and logarithmic power spectrum plot 4: Plots for different values for N 5: Mel Space 6: Modified spectrum 7: 2D plot of accustic vectors 8: Plot of the 2D trained VQ codewords 9: Recognition rate of the computer and so on.....

说明：  通过直接分析声音文件得到最大似然估计法下的混响时间和混响时间的图像，房间空间的参数来自AIR数据库，数据库里面有多种房间形式的参数形式。(Through the direct analysis of sound files, the images of reverberation time and reverberation time under the maximum likelihood estimation method are obtained. The parameters of room space come from air database, which has many kinds of room forms.)

说明：  BP神经网络的仿真，能够拟合各种函数，支持梯度下降法和LM两种训练算法。所有代码自己编写，没有使用matlab自带的函数，是学习的最佳范本。(The simulation of BP neural network can fit various functions and supports two training algorithms, gradient descent method and LM. All the code is written by myself, without using the functions that come with matlab, it is the best model for learning.)

卡尔曼滤波，很有用。和维纳滤波比较。程序代码，丰富。大家可以多学习(Kalman filtering, very useful. And Wiener filtering comparison. Program code and rich. We can learn more)
