基于元胞自动机模拟的渗流集群，非常好的一个程序。。(Celluar automation-- PercolationCluster. It is a very excellent program..)

说明：  北航数值分析大作业第一题：矩阵的QR分解求特征向量。代码是我在理学院本科期间写的，所有结果已经过Matlab及Mathematica验证，保证算法正确实现。(Numerical analysis of Beihang great job the first question: QR decomposition of matrix eigenvector. Code is written during my undergraduate logical Institute, all results have been verified through Matlab and Mathematica, to ensure it is correct to achieve.)

用于产生Gabor信号的程序，直接调用即可(used to proceed Gabor signal, and it is very useful in signal processing)

利用SVM做回归线性测试。对于大盘指数的有效预测可以从整体上观测股市的变化提供强有力的信息，所以对上证指数的预测很有意义。通过对上证指数从1990.12.20-2009.08.19每日的开盘数进行回归分析，最终拟合的结果是：均方误差MSE=2.35705 e-005，平方相关系数 R=99.9195 。SVM的拟合结果还是比较理想的。(Make use of SVM linear regression testing. For the market index can predict the observed changes in the stock market as a whole to provide a strong information, so it makes sense to predict the Shanghai index. Through the Shanghai Composite Index opened daily from 1990.12.20-2009.08.19 number of regression analysis, the results of the final fit are: mean square error MSE = 2.35705 e-005, the square of the correlation coefficient R = 99.9195 . SVM fitting result is quite satisfactory.)

动态电力系统次同步谐振.次同步谐振一是交流输电系统中由串联电容补偿引起的次同步谐振问题，二是由一些电气装置引起的次同步振荡问题。次同步振荡会使轴系产生很大的扭矩，严重情况下可能导致大轴出现裂纹甚至断裂， 或因反复承受较大转矩造成疲劳积累， 使轴系寿命降低。因此，对次同步振荡进行准确的分析和计算， 采取有效的监视、防止和保护措施是非常重要的。程序是对交流线路串补偿电容引起的次同步振荡抑制的编程。(dynamic power system subsynchronous resonance.)
