matlab例程 bp神经网络训练算法(BP neural network training algorithm)

基于BP网络的分类方法，针对网上的BP分类没有权值调整的缺陷做了改进。(BP network based classification method for web-based BP classification not have the right to adjust the value of the shortcomings have made improvements.)

说明：  更新部分 1、自适应算法采用参考文献[2]的NLMS算法，收敛速度更快，所需训练次数更少。 2、自适应收敛步长在(0,2)之间存在较优取值，Lorenz序列为0.6。(update an adaptive algorithm reference [2] NLMS algorithm, convergence faster, less the number of required training. 2, adaptive step in the convergence of (0,2) between the optimum value, Lorenz sequence of 0.6.)

说明：  射线追踪Matlab演示程序，完美可运行(Ray tracing matlab demonstration program, perfect for operation)

这是一个关于BPSK的代码编程，有兴趣的读者可以关注一下！！！(BPSK)

matlab实现的MME（modified matrix encoding）隐写算法 可成功运行(the MME (modified matrix encoding) steganographic algorithm which can successfully run)

2DPSK的链路仿真，信号源的产生，PCM编码，调制解调以及加燥 (2 dpsk link simulation signal source, PCM coding and modulation demodulation and dry)

matlab 数值处理实例,应用于各种数值处理算法，有相应的程序目录.(matlab numeric computation examples, with various numeric methods inclued.)

this is simple qpsk for matlab code

极值学习机，一种最近流行的算法。它的使用，使得计算过程大大的简化，值得交流分享。(Extreme Learning Machine, a recently popular algorithms. Its use, so that the calculation process is greatly simplified, worth sharing.)
