CVPR2009 FLOW CODE IT IS USEFUL TO SOMEONE WHO WANT TO STUDY OPTICAL FLOW(CVPR2009 FLOW CODE)

求600的阶乘，并且能输出其中能被9整除的数的个数。(divide)

利用Matlab实现光学系统光线追迹功能(Ray tracing of optical system with matlab)

读取radarsar数据的MATLAB程序(MATLAB program to read the data radarsar)

2fsk的调制信号在matlab里的仿真实现(2fsk modulation signal simulation in Matlab)

该算法，解决了不收敛的问题，聚类效果非常好。改进的蚁群算法是基于遗传算法的改进，在基本遗传算法的基础之上，加入了变异因子，产生变异，从而更快的收敛。(The algorithm solves the problem of convergence, and the clustering effect is very good. The improved ant colony algorithm is based on the improvement of genetic algorithm. On the basis of the basic genetic algorithm, the variance factor is added to produce the variation, and the convergence is faster.)

自己做用FPGA实现VGA显示时，图像提取信息的matlab程序！！！(FPGA realization of their own with VGA display, the image information extraction matlab program! ! !)

主要是数学中的各种算法，主要包含拟值优化，微分方程求解等算法实现。(math algorithm)

LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G) (LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)

说明：  详细的介绍了音频模糊聚类的算法，非常的容易搞懂(Detail audio fuzzy clustering algorithm, the easier they get to know very much)
