VRE-PCA

算是一个小小的教程，交给初学者如何使用matlab，进行聚类分析，里边包含源码及示例。(Is a small tutorial to the beginners how to use Matlab, cluster analysis, and the inside contains the source code and examples.)

说明：  可用来求解多仓库的车辆路径问题，经测试可直接运行(This program can be used to solve the vehicle routing problem of multiple warehouses, and can be directly run after testing)

说明：  利用理论推导的方法，该matlab程序得出涡旋光束经相位全息光栅接收后一阶衍射光束的解析表达式。(By using the method of theoretical derivation, the analytical expression of the first-order diffraction beam of vortex beam received by phase holographic grating is obtained by MATLAB program.)

this code implement a fingerprint recognition method

本程序利用球形不变随机过程法模拟产生服从瑞丽分布的海杂波，适合实验室环境下做为海杂波的输入信号。(The program uses the same random process simulation of spherical produce the distribution of sea clutter obey Ruili, suitable for sea clutter under laboratory conditions as the input signal.)

Kernel自适应滤波器算法是基于Kernels的在线自适应回归算法。非常适合非线性滤波，跟踪和回归。该工具箱包括算法，演示和性能比较工具(Kernel adaptive filtering algorithms are online and adaptive regression algorithms based on kernels. They are suitable for nonlinear filtering, prediction, tracking and nonlinear regression in general. This toolbox includes algorithms, demos, and tools to compare their performance.)

利用matlab开发的偏微分方程图形图像处理小程序，效果非常好，简单易用(using Matlab development of the PDE small graphic image processing procedures, the effect is very good, simple and easy)

一本介绍matlab学习的书籍，清华出版 高清，非常有用(An introduction to the MATLAB learning books, Tsinghua publishing HD, very useful )

以r=6 1 103F为基础，抽取出其他m序列，在生成的m序列集中，寻找出m序列优选对，确定优选对数量，并画出它们自相关和互相关函数图形；(Based on the r = 6 1 103 f, extract other m sequence, concentrated in the generated m sequence, selection to find the m sequence, determine the optimum number of, and draw them autocorrelation and cross-correlation function graph )

模拟信号的数字化传输---增量调制系统 用SIMULINK建立简单增量调制系统的模型并进行 （3） 正弦信号 （4） 语音信号 的传输。 改变抽样频率和量化台阶大小，观察重建信号以及量化噪声信号的波形；对于语音信号主观评价声音质量的变化。 (Digitized analog signal transmission systems--- delta modulation delta modulation SIMULINK easy set up of the model system and (3) sinusoidal signal (4) transmission of voice signals. Change the sampling frequency and quantization step size, to observe the reconstruction of signal and quantization noise signal waveform for subjective evaluation of the speech signal changes in sound quality.)
