interpolation

划分网格一个开源的库，有限元的算法，很好用(Meshing an open source library = for finite element)

说明：  用FORTRAN语言实现二维欧拉方程的求解，采用二阶MUSCL迎风格式()

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)

这些代码可以用于产生一系列随机数，可以根据需要使用。(These codes can be used to generate a series of random numbers may be used as needed.)

对平面上给定的多点进行多项式曲线的拟合，可设置拟合多项式的次数(Given more points on the plane polynomial curve fitting, you can set the number of polynomial fitting)

一维的N_S方程的求解程序，是计算流体力学的算例(the N_S equation of one dimension .)

数值分析中三次样条插值算法，运行稳定，并能画出最后的插值曲线(Numerical Analysis of cubic spline interpolation algorithm, running stability, and can draw the final curve interpolation)

经典R-K法，通过它可以计算一些简单的常微分方程的数值解(Classical RK method, which can be calculated by simple numerical solution of ordinary differential equations)

FLUENT里面改进的SA湍流模型，为UDF文件，可以进行链接编译计算(FLUENT which improved SA turbulence model for the UDF file can be compiled to calculate the link)

用VBA在Excel里实现分级计算，实现通过年终奖和月收入计算个人所得税的功能。数据为2012年最新的标准，对于会计电算化人员有非常强的实用性。(VBA in Excel to achieve grade calculated to achieve the functionality of the calculation of personal income tax through the end of the year Award and the monthly income. The data for 2012 the latest standards, computerized accounting personnel have a very strong practicability.)
