利用matlab内的svd function来拆解脸部图型并计算出在重新构制中会碰到的错误数量(Use of matlab' s svd function to disassemble the face graphics and calculate the re-structure the system will encounter in the number of errors)

用MATLAB自带的工具箱实现svm的多分类问题，代码有注释。(MATLAB comes with the toolbox to achieve svm multi-classification problem, the code has comments.)

说明：  BP_Adaboost模型即把BP神经网络作为弱分类器，反复训练BP神经网络预测样本输出，通过Adaboost算法得到多个BP神经网络弱分类器组成的强分类器，利用此方法设计出强分类器。(The BP_Adaboost model uses the BP neural network as a weak classifier, repeatedly trains the BP neural network to predict the sample output, and uses the Adaboost algorithm to obtain a strong classifier composed of multiple BP neural network weak classifiers. This method is used to design a strong classifier.)

说明：  matlab与dsp之间进行udp通信的matlab程序，包含了自己的理解注释，可以实现简单的报文接收，并可以根据自己的需要进行实时的matlab报文数据处理解析。欢迎交流。(Matlab program for UDP communication between MATLAB and DSP contains its own understanding notes, which can realize simple message receiving and real-time matlab message data processing and analysis according to their own needs.)

Matlab 自定义窗函数的幅频分析，包括矩形窗，三角窗，汉宁窗，汉明窗等(Matlab customize the width of the window function frequency analysis, including rectangular windows, triangular windows, Hanning window, Hamming window, etc.)

本文当中包含了matlab的主要命令，如管理命令和函数(This article contains the main matlab command, such as management commands and function)

应用于matlab支持向量机svm的工具箱(Applies to support vector machine SVM matlab toolbox)

用MATLAB实现的卡尔曼滤波，根据有用信号和干扰噪声的统计特性（自相关函数或功率谱），以线性最小均方误差（MSE），能最大程度的滤除干扰噪声，提取有用信号。(Kalman filter using MATLAB, based on the statistical properties of the useful signal and interference noise (autocorrelation function or power spectrum), linear minimum mean square error (MSE), filter out noise interference to the greatest extent, to extract the useful signal.)

Lsl算法是数字预失真的一种重要算法，一种自适应算法(Lsl algorithm is an important digital pre-distortion algorithm, an adaptive algorithm)
