用matlab编的朝里计算 牛顿拉夫逊直接坐标 解潮流(Matlab compiled by North Korea in the calculation of Newton Raphson solution directly coordinates the trend)

关于MATLAB的经典教程，很全面，包含所有的关于MATLAB语言的规则等！(Tutorial on MATLAB classic, very comprehensive and include all on the MATLAB language rules!)

信息隐藏的函数，matlab 编写，简单方便(A function of information hiding, matlab prepared, simple and convenient)

说明：  数字通信调制信号模拟系统中常见通信信号的信号源(Digital communication modulation signal simulation system common source of communication signals)

这是一道很基本的程序，一方面希望它对初学遗传算法的兄弟们有用（包含了遗传算法实现的大部分步骤，而且有详细的注释），另一方面旨在抛砖引玉， 在下浅见： 1、遗传算法在进行大规模计算时，数据交换量大，速度确实是一个瓶颈，就如这道程序，在种群规模50，进化代数1000时运行需要40秒左右(cpu:duron 1G),当然，小弟编程能力弱，望各位大侠指教啊，或帮我修改一下这道程序 (This is a very basic procedure, While they want it beginner GA brothers useful (including the genetic algorithm to achieve the most steps and a detailed note), on the other hand aims to attract the next suggestions : 1. GA conducting large-scale calculations, the data exchange capacity, speed is a bottleneck, as this practice. 50 in population size, the evolution of algebra required for the operation of 1000 when about 40 seconds (cpu : duron 1G), Of course, the younger programming weak, and hopes to enlighten ah Shanhaiguan, or help me rephrase this practice)

hardware implementation of digital filters for signal processor

利用k-means的算法实现图像区域分割，主程序只能运行灰度图像，彩色图像需另写调用程序(Using the k-means algorithm for image segmentation, the main program will only run grayscale image, color image subject to write the calling program)

实现遗传算法的基本历程，可以自由修改变异概率，交叉概率，迭代次数等(Basic Course genetic algorithm, can be freely modified mutation probability, crossover probability, the number of iterations)

基于离散余弦变换（DCT）的数字水印源代码包括水印生成、嵌入、提取等(Based on the discrete cosine transform (DCT) of the digital watermark source code including the watermark generation, embedding, extraction, etc.)

这里有一个OQPSK的源代码，不错的，可以直接使用，需要的可以下载(There is a OQPSK the source code, well, you can directly use, in need can be downloaded)
