一个模式分类的工具箱，matlab语言实现，对模式识别相关方向的人很有用(pattern classification of a toolbox, Matlab language, pattern recognition related to the direction of useful)

说明：  This file usesd Hopfield network to store patterns and to recall the full patterns based on partial input.

copula函数 模型建立 相关性分析 模型拟合检验(Establishment of correlation analysis by copula function model)

说明：  本书是比较好的matlab学习资料 可以帮助初学者掌握基本的编程，里边也包含了程序源是很方便的。(This book is a good matlab learning material to help beginners master the basic programming, which also contains the program source is very convenient.)

该程序是在matlab环境下对加性高斯白噪声信道的无线通信中的直接序列扩频系统进行仿真。(The program is in the matlab environment of additive white Gaussian noise channel in the wireless communications system for direct sequence spread spectrum simulation.)

Consider a BPSK and a QPSK system for the following two cases: 1) The probability that the symbol 1 is sent and the probability that the symbol 0 is sent are all the same. 2) The probability that the symbol 1 is sent is two times than the probability that the symbol 0 is sent. Assume that the noise is Gaussian distributed with mean=0 and  2 = 1.

说明：  利用matlab处理数据.采用FFT和小波分析的方法分析信号的功率谱.........(perform on the picture using matlab to analysis the power spectrum...)

structural steganalysis(sp/ws) for testing steganographi algorithm

文章中的信道MIMO信道的容量推导，非常适合初学者理解，在下就是一名小白，还是看懂了，比较好的资料，不过没有matlab的仿真代码。(The channel MIMO channel capacity deduction in the article, very suitable for beginners to understand, in the next is a white, or understand, better information, but no matlab simulation code.)

角度和时延联合估计（JADE）算法MATLAB程序,适合学习(Joint angle and delay estimation (JADE) algorithm MATLAB program for learning)
