模糊c-均值聚类算法通过优化目标函数得到每个样本点对所有类中心的隶属度，从而决定样本点的类属以达到自动对样本数据进行分类的目的，一般用于故障识别与分类。(Fuzzy c- mean clustering algorithm obtains the membership degree of every sample point to all class centers by optimizing the objective function, and determines the classification of the sample points to achieve automatic classification of sample data. It is generally used for fault recognition and classification.)

本文利用MATLAB的可视化工具箱simulnk建立了直扩通信系统的仿真模型，为扩频信号源自检程序设计提供参考。(In this paper, the visualization MATLAB toolbox simulnk DSSS communication system established a simulation model for the spread spectrum signal self-test program designed to provide information.)

Matlab实现绘制任意自由曲线，实现Photoshop中的钢笔路径功能，用光顺连接的B样条/贝塞尔曲线实现，鼠标点击生成控制点，拖动形成任意曲线。可描绘多路径，也可旋转、平移、缩放。经调试可用。(Matlab achieve rendering arbitrary free curve, realize the pen path function in Photoshop, with the light of the B spline/Bessel curve, the mouse click to generate control points, drag to form any curve. Can depict many paths, but also can rotate, translation, scaling. Debug available.)

现有的几个网络拓扑随机发生器，其实很难生成理想的网络拓扑结构，其主要原因在于很难控制节点的疏密和间距。我们提出来的这个改进算法，在随机抛撒节点的时候使用了K均值聚类，由本算法作为网络拓扑发生器，网络节点分布均匀且疏密得当，边的分布也比较均衡(The few existing random network topology generator, is in fact very difficult to generate the desired network topology, the main reason it is difficult to control the node density and spacing. We put forward the improved algorithm, throw in random nodes when using the K-means clustering, by the algorithm as a network topology generator, network nodes and spacing evenly distributed properly, the edge of a more balanced distribution of)
