matlab 读取操作图片，可以打开图片，改变其显示模式(matlab read operation picture, you can open the picture, and changing the display mode)

自组织特征映射模型(Self-Organizing feature Map)，认为一个神经网络接受外界输入模式时，将会分为不同的区域，各区域对输入模式具有不同的响应特征，同时这一过程是自动完成的。各神经元的连接权值具有一定的分布。最邻近的神经元互相刺激，而较远的神经元则相互抑制，更远一些的则具有较弱的刺激作用。自组织特征映射法是一种无教师的聚类方法。(Self-organizing maps model (Self-Organizing feature Map), that a neural network to accept outside input mode, will be divided into different regions, the regional input modes have different response characteristics, while the process is done automatically . The connection weights of neurons with a certain distribution. Nearest neurons stimulate each other, while distant neurons are mutually inhibitory, with a further some of the weaker stimulus. Self-organizing feature map method is a clustering method without teachers.)

说明：  用Matlab实现灰度图像SIFT（尺度不变特征变换）特征点的提取(Grayscale images with Matlab SIFT (Scale Invariant Feature Transform) feature point extraction)

这几个程序可以实现加窗后对信号滤波，包括凯泽窗，汉明窗，矩形窗(This several programs can realize add window to signal after filtering, including the Kaiser window, han Ming window, rectangular window )

维纳滤波的一个应用 是关于AR(4)模型的(An application of Wiener filtering is on the AR (4) model)

设计了信息在空间传输的莱斯信号模型,当接收端存在一个主要的静态信号时，如LOS分量（如在郊区和农村等开阔区域中）等，此时接收端接收的信号的包络就服从Rician分布。(Rician signal model)

说明：  sift特征匹配代码，并带有相关说明文档(SIFT feature matching code with relevant documentation)

计算机控制的matlab例程 自己做的关于课程的仿真程序(Computer-controlled matlab routines to do their own on the course of the simulation program)

图论，最小生成树，一种数学建模的实用方法，对你的比赛，和应用很有帮助(Graph theory, the minimum spanning tree，A good mathematical modeling tool, It is very helpful to your study MATLAB)

利用时域有限差分法(FDTD法)对二维时谐电磁场进行模拟(Using finite difference time domain method (FDTD method) on two-dimensional time-harmonic electromagnetic field simulation)
