随机数生成程序，该随机数呈zipf分布，就是大家常说对于内容的访问遵循80/20原则，也就是20 的内容，会占有80 的访问量。(Random number generator, the zipf was distributed random numbers, that is, we often say that the access to the content to follow the 80/20 principle, which is 20 of the content will occupy 80 of visits.)

这是一段杆塔建模的命令流，可用于ansys有限元分析(This is a tower of order flow modeling, finite element analysis can be used to ansys)

数值分析，即计算方法课程中的龙贝格算法源代码。(Numerical analysis, calculation of the Romberg algorithm source code in the methods courses.)

最优解回溯法0-1问题，为了构造最优解，必须在算法中记录与当前最优值相应的当前最优解。(The optimal solution backtracking 0-1 must be recorded in the algorithm, in order to construct the optimal solution, corresponding to the current optimal value, the current optimal solution.)

数值计算实例，主要有LU分解，龙格库塔法，高斯分解法，欧拉法，曲线拟合，曲线插值(Numerical example)

说明：  曲线的三次样条插值，在非首尾节点处具有三次光滑性质(Curve cubic spline interpolation, in both nodes with non-smooth nature of the three)

基于C环境下的最小二乘法的计算编程算法相当相当实用。(C based on the circumstances of the least squares algorithm for calculating the programming very well.)

vc++实现编译原理中的LL(1)文法的编译过程,非常好用.(vc realization of the principle of compiler LL (1) grammar compiler course, very handy.)

测绘程序，计算测边网各点坐标的评查程序，值得借鉴(Mapping program to calculate the coordinates of each point measured the side-netting of assessment investigative procedures, worth learning)

计算岩石表面裂隙宽度并求取其表面粗糙度系数(Calculate the rock surface crack width and strike the surface roughness coefficient)
