matlab程序设计的数据库连接，有利于初学者了解MATLAB的编程思想与方法，使初学者快速入门(Matlab program design of the connection, be helpful for beginners to learn matlab programming thought and method, make the beginner quick start)

I want to state that according to my previous month bill (M/S Gangesh kumar A/C no 400363210)was approx. INR 300 TO 400 But in month of august its INR 2000 .when complain was lodged to RO they said its software fault

这里实现了图像除噪声的算法，各种模板算子。(Here to realize the image noise than the algorithm, various template operator.)

粒子群优化算法优化无约束函数，其优化效果相当的不错，呵呵呵呵！(AVERAGE PSO Programs constrain gear Design)

多用户MIMO中的块对角化，主要用来消除用户间的干扰(Block Diagonalization for Multi-User MIMO)

根据D.C.CHU提出的计算CAZAC序列的算法，计算出CHU序列的matlab程序。包括自相关函数，FFT变换后的CHU序列，以及CAZAC序列的一些特性，还提供D.C.CHU的算法原文(According to the calculation made by CAZAC sequence DCCHU algorithm to calculate the CHU sequence matlab program. Including the self-correlation function, FFT transformed CHU sequence, as well as some of the characteristics CAZAC sequence)

关于matlab的简单的小例子，希望可以对初学者有一定的指导作用(On simple little example matlab hope can have some guidance for beginners)

数学实验，聚类分析---用matlab做聚类分析，整个聚类实验的详细步骤，适用于学习算法的初学者(The mathematical experiment: cluster analysis--- do a cluster analysis using matlab)

一个有效的实现k - means+ +聚类多元数据算法。已经证明,这种算法有一个预期值的上界值。此外,k - means + +具有较好的收敛性。(An efficient implementation of the k-means++ algorithm for clustering multivariate data. It has been shown that this algorithm has an upper bound for the expected value of the total intra-cluster distance which is log(k) competitive. Additionally, k-means++ usually converges in far fewer than vanilla k-means.)

BCJR decoder，inputs are source bit,coded bit, and a priori, outputs are source bit and coded bit (a posteriori)(There s an array named table inside, describe the trellis, five column is: start state, destination state, source bit,coded bit 1,coded bit 2, respectively.)
