matlab实现极大似然估计法定位无线传感器网络节点。(matlab maximum likelihood estimation method to achieve positioning of wireless sensor network nodes.)

这是一本matlab学习课件书籍，其中包括一些基本的操作，也包括相当多的源程序(This is a matlab learning courseware books, including some of the basic operations, including a considerable number of the source)

说明：  物流选址matlab代码，简单易懂，有注释。(Logistics choose matlab code, easy to understand.)

说明：  直接扩频序列的仿真 bpsk调制解调 有图示说明(DSSS simulation)

粒子滤波的Matlab例程，可实现基本的例子滤波算法(Matlab routines particle filter can be realized example of the basic filtering algorithm)

利用互相关法进行单目标的时延定位，并给出仿真结果(Cross-correlation method using a single target latency positioning, and simulation results)

直方图均衡：原始图的直方图变换为均匀分布的形式，这样就增加了象素灰度值的动态范围从而达到增强对比度的效果 中值滤波：中值滤波属于非线性平滑滤波器，它可以消除噪声又能保护图象的细节(histogram equalization : the original plan to transform the histogram in the form of uniform distribution. This will increase the value of the pixel gray areas so as to achieve dynamic contrast enhanced effect of filtering : Median filter is nonlinear smoothing filter, it can eliminate noise while preserving image details)

求网络图中各节点的聚类系数及整个网络的聚类系数 求解每个节点的聚类系数，找某节点的所有邻居，这些邻居节点构成一个子图(Seeking clustering coefficient network diagram and the entire network clustering coefficient of each node)

用元胞自动机模拟博客圈里舆论的传播过程，可得到最终结果图形。(Analysis of the propagation of discussion topics in the blogosphere with CA)

模糊综合评判计算程序 模糊综合评判的过程：1、灰色关联分析，求权重（程序见Relation）；2、模糊聚类分析，划分等级（程序见F_class）；3、隶属度计算，求隶属函数（程序见Subjection和subject）；4、模糊综合评判，计算各单元等级（程序见F_judge）。(Fuzzy comprehensive evaluation matlab code The process of fuzzy comprehensive evaluation: 1. Grey relational analysis to get weight (see Relation for program); 2. Fuzzy clustering analysis to divide ranks (see F_class for program); 3. Membership degree calculation to get membership function (see Subjection and subject for program); 4. Fuzzy comprehensive evaluation to calculate each unit grade (see F_judge for program).)
