This programs are very useful for time prediction.

说明：  接收端选择性多样化，用于优化瑞丽信道的衰落，减少误码率(selection diversity)

说明：  模糊c均值（fcm）实现无监督聚类算法，经本人尝试，程序可以正常运行(Fuzzy C-means (FCM) to achieve unsupervised clustering algorithm, I try, the program can run normally)

Fisher线性判别是线性分类算法中最基本的一种算法，其基本思想是将d维空间中的样本投影到一条最易于分类的投影线上，再进行分类。本文将用使用matlab实现Fisher线性判别算法，并给出４种阈值选择的方法。(Fisher Linear Discriminant is a linear classification algorithm as a basic algorithm, its basic idea is to d-dimensional space of the samples are projected onto one of the most easily classified projector online, and then classified. This article will use matlab to achieve Fisher Linear Discriminant algorithm, and gives four kinds of threshold selection method.)

说明：  matlab 科学计算与可视化程序集。几百个小程序供初学者掌握matlab的科学计算十分有帮助。(matlab scientific computing and visualization of the assembly. Hundreds of small programs for beginners to master the scientific computing matlab very helpful.)

说明：  自己写的Canny算子的matlab实现和演示。程序虽然不大，但相信也能给大家一些参考。 (himself wrote the Canny Operator Matlab realization and demonstration. Procedures not much, but I believe that can give you some information.)

是一个关于OFDM仿真的小程序，比较小的程序，可以拿来练练手(It is a little on the OFDM simulation program is relatively small program that can be used to practice your hand)

基于遗传算法的非线性规划的函数寻优算法。(Function optimization algorithm Nonlinear Programming Based on Genetic Algorithms.)

显示一个经验概率密度函数在输入数组中的密度分布直方图X的使用nbins箱的数目（默认pdfplot套nbins至20）。如果输入X是一个矩阵，然后pdfplot（X）的分析它的载体，并显示所有值的PDF格式。对于复杂的输入X，pdfplot（X）的显示PDF格式的(displays a histogram of the empirical probability density function (PDF) for the data in the input array X using nbins number of bins (by default pdfplot sets nbins to 20). If input X is a matrix, then pdfplot(X) parses it to the vector and displays PDF of all values. For complex input X, pdfplot(X) displays PDF of abs(X). )
