Richardson
里查得森(Richardson)法解偏微分方程的程序。解的是定步长的抛物型偏微分方程:
du/dx - a * d2u/dx2 = 0
在程序中可以更改 a 的值以实现不同系数的解。由于它是一种显式格式,解的结果不稳定
在Matlab7下面运行发现竟然有一些值达到十的几十次方,这是算法本身决定的。不是程序有错误(Richard Anderson (Richardson) Solving partial differential equations procedures. Solution is scheduled to step parabolic partial differential equation: du/dx- a* d2u/dx2 = 0 in the procedure can be changed in order to realize the value of a different coefficient of the solution. Because it is an explicit format, the result of instability in the solution of the following Matlab7 running even found some value reached ten dozens of parties, this is the decision algorithm itself. Not a procedural error)

说明: 对标准卡尔曼滤波方法中野值对其滤波精度的影响,提出了基于M估计的野值
处理方法。这种方法不仅可以去除单个野值的影响,而且在野值成片出现时还能很好地保持滤波
稳定性。通过仿真验证了该方法的有效性。(Their filtering accuracy on the standard Kalman filtering method outliers, outliers based on M-estimation approach. This method can not only remove the impact of individual outliers, and opposition values into the film appears to keep the filter can be very stability. The effectiveness of the method is verified by simulation.)

基于PSO LSSVM的预测程序
基于pso_lssvm的预测程序,直接可用,可以出图,可以修改。加入了粒子变异、权值的递减策略(去掉%就行了)。注意:excel记得放对位置(Pso_lssvm based prediction program, directly available, you can map, you can modify. Added a particle mutation, weight reduction strategy (remove%))
