使用低通滤波器，观察原始图像与以图形形式显示的高斯低通滤波器的差别，显示频谱和处理后的图像！(Using low-pass filter to observe the original image and displayed in graphical form of the difference between the Gaussian low pass filter, display the spectrum and the processed image!)

matlab 模糊工具箱函数，包含含了大部分的模糊工具箱函数，非常实用 (matlab fuzzy toolbox functions, including containing most of the fuzzy toolbox function, very useful)

基于MATLAB/Simulink建立2RC等效电路模型，用于电池模型参数辨识(2RC equivalent circuit model for battery model parameter identification)

说明：  k-means算法实现图像分割 根据输入的类别数量来计算类别平均值(k-means algorithm for image segmentation This program gets an image and the desired number of partitions and finds the means of the different classes and provides a classified image.)

四种聚类算法源代码及示例代码,本程序的最终目的是形成一套标准的用于聚类、可扩展的工具。包括的内容有1. 聚类算法：Kmeans和Kmedoid算法、FCMclust, GKclust, GGclust算法 2. 评估分类原型：程序可以在二维图像上绘制出聚类的结果 3. 验证：程序给每一个算法提供验证机制，每个聚类算法会统计(Partition Coefficient (PC), classification Entropy (CE), Partition Index (SC), Separation Index (S), Xie and Beni s Index (XB), Dunn s Index (DI) and Alternative Dunn Index (DII)几种衡量指标。-Four kinds of clustering algorithms source code and sample code, the ultimate goal of this program is to form a set of standards for clustering, scalable tools. Including the contents of a. Clustering algorithm: Kmeans and Kmedoid algorithms, FCMclust, GKclust, GGclust algorithm 2. Assessment classified prototypes: programs can be plotted in two-dimensional image, the results of clustering 3. Verify: Program to provide an algorithm to each authentication mechanism, each clustering algorithm will calculate Partition Coefficient (PC), classification Entropy (CE), Partition Index (SC), Separation Index (S), Xie and Beni s Index (XB), Dunn s Index (DI) and Alternative Dunn Index (DII) of several metrics.)

说明：  这是国外一本经典教材附带的程序，通信系统的matlab实现，所含例子丰富(This is a classic foreign materials attached to the procedures, communications systems to achieve matlab contains abundant examples of)

说明：  关于数字信号处理的matlab小作业。初学者可以看看。高手就算了。。。。(Matlab on a small digital signal processing operations. Beginners can look at. Even the master. . . .)
