一个用拟牛顿算法求解优化问题的程序，此程序为MATLAB程序，大家用前自己注意检查一下(A Quasi-Newton algorithm using optimization procedures, the procedures for the MATLAB program, we pay attention to before their own check)

几种计算阶乘、阶乘之和的算法，由于计算机存储问题，一般阶乘不可能算得太大，只是一种方法。(Several computing factorial, factorial, and the algorithm, due to computer storage problems, the general factorial can not be considered too great, is only a way.)

说明：  本程序可计算二维光子晶体的带隙，并得出带隙图，和带隙位置及宽度(This procedure computable two-dimensional photonic bandgap crystals, and came to the band-gap maps, and the band-gap position and width)

计算流体力学中运用有限体积法求解二维无粘欧拉方程，非结构网格(CFD finite volume method for solving two-dimensional inviscid Euler equations, unstructured grids)

矩阵按键程序，用的是C。本人还是学生，做得不好请大家多多指教(Matrix button procedure is used in C. I am still a student, doing a lot of bad advice please)

圆柱绕流的数值模拟（基于有限体积法），Fortran程序(Numerical simulation of flow around a cylinder (based on the finite volume method), Fortran program)

说明：  球形粒子Mie 散射用Matlab编写的Mie theory计算程序。在光子学中运用广泛，使用非常方便(Mie scattering of spherical particles prepared by using Matlab program Mie theory. In the use of photonics in a wide range of very convenient to use)
