学习如何设置UPML吸收边界的3-D FDTD程序.对于初学者很有帮助(Learn how to set up UPML absorbing boundary of the 3-D FDTD procedure. Very helpful for beginners)

用四阶龙格库塔法计算Lorenz混沌系统的时间序列(The time series of Lorenz chaotic system of fixed step size fourth-order Runge-Kutta method algorithm source code.)

本例实现了插值函数，将不同次数的插值进行了显示，防止了龙格现象，研究生一般以此题为作业。(The cases to achieve interpolation function, the number of different interpolation were shown to prevent the Runge phenomenon, in order to graduate generally entitled operations.)

一元稀疏多项式编程，希望对大家的编程有点用，欢迎下载(hope it useful to you)

C-N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。在循环中改变 a 的值以实现变系数. 该说明在压缩包是也有(CN solution of 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. Change in the cycle in order to realize the value of a variable coefficient. The note in the compressed packet is also)
