遗传算法的实数编码MATLAB程序，不是工具箱，有助于理解遗传算法的编程实现(Genetic algorithm written by maltab)

本程序可用于计算电力系统可靠性指标ENS。不同于一般用平均负荷的方法，考虑了负荷的动态响应。(To calculate the reliability index of distribution system.)

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.)

利用幂法求矩阵特征值，属于数值解法的一种(Using power method to find eigenvalues of matrices, which is a kind of numerical solution.)
