基于MATLAB的双音多频信号DTMF的生成。(MATLAB-based dual-tone multi-frequency DTMF signal generation.)

这是我们参加2011年全国大学生数学建模大赛，做A题的论文和matlab程序，当年获得国奖。 利用此程序可以进行污染源位置反演计算，以及其他类似服从高斯扩散模型的源项反演。 计算量小，简单易懂。(Detect of Pollution source in city.2011 China Undergraduate Mathematical Contest in modeling Q_A.)

这几本是关于Matlab开的书籍，对于初学者很适用(Several open books on Matlab, it is suitable for beginners)

SVM（支持向量机）参数寻优代码，可自动实现支持向量机的参数寻优(SVM (support vector machine) parameter optimization code that can automatically support vector machine parameter optimization)

软件用来进行m-k的秩相关系数，用于分析趋势(Software used to mk' s rank correlation coefficient, used to analyze trends)

本程序为粒子群优化算法，可用于优化计算，能够运行。(Particle swarm optimization algorithm)
