this is one of the more powerful algorithm in Clustering in WSN. It seems very different from LEACH and other probabilistic approaches.

1. 程序中Turbo译码采用了MAP,LOG-MAP，和MAX-LOG-MAP三种算法。 2. 以xxx开头的四个mat文件是四种给定的Turbo码在译码时用到的参数，保存下来的目的是 加快仿真的速度，如果你所仿真的Turbo码不是程序中列出的任意一种，你可以通过函数 trellis来生成自己的相关参数。 3. 程序支持1/2和1/3两种码率的Turbo码，其中1/2码率的Turbo码通过矩阵[1 0 0 1]打 孔得到。在译码时通过对打孔位置添0恢复成1/3码率的码字。 4. 程序中的信噪比表示Eb/N0，通过此参数求得N0，对发送信号进行加噪。(1 program in Turbo decoding using the MAP, the LOG-MAP, and three kinds of the MAX-LOG-MAP algorithm.)

这是个有关QOS组播路由的的实例代码，希望大家喜欢！(this is a )

是matlab的代码，关于yann Lecun在89年提出的cnn的原型，这个代码成功应用于欧洲很多国家的手写支票识别(Is matlab code on cnn yann Lecun prototype made in 1989, this code successfully applied to handwriting recognition check many European countries)

by using this source code we can detect the edges of the image...which helps in the medical field and in satellite.

能够从单一的图像中提取出镜面反射的内容。改算法使用matlab编写，非常值得研究的算法。(From a single image to extract the contents of specular reflection. Matlab algorithm to use to prepare, the algorithm is very worthy of study.)

最经典AdaBoost实现，适合初学，有大量详细的注释，容易理解(This a classic AdaBoost implementation, in one single file with easy understandable code. The function consist of two parts a simple weak classifier and a boosting part: The weak classifier tries to find the best threshold in one of the data dimensions to separate the data into two classes-1 and 1 The boosting part calls the classifier iteratively, after every classification step it changes the weights of miss-classified examples. This creates a cascade of "weak classifiers" which behaves like a "strong classifier" 。)

巴特沃斯和切比雪夫滤波器,其中前者为低通,后者为带通,可有效滤除不同频噪声.(Butterworth and Chebyshev filter, where the former is a low-pass, band-pass which can effectively filter out different frequency noise.)
