udf_dpm_tongji

基于OpenMP的大型矩阵相乘的算法源码(Based on OpenMP for large matrix multiplication algorithm source code)

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.)

四阶龙格库塔法，用C++编写，很有参考价值(Fourth-order Runge-Kutta method, written in C, a good reference)

fluent中用于修改湍流粘度系数的自定义函数(udf to modify turbulence viscosity coefficient in fluent)

这是用C++做矩阵求逆和矩阵相乘，可以解简的线性方程。已验证，互相交流~(This is done using C++ matrix inversion and matrix multiplication, linear equations can be solved。)

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)

计算机流体理论方面的文献，动网格的划分和计算(Literature, of the theory of computational fluid dynamic division and calculation of the grid)

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)

进行结构响应分析的Wilson法，是直接积分的基本算法之一，相信进行有限元动力分析编程的诸位都能用上(structural response analysis of Wilson, which is direct integration one of the basic algorithm, believe that the dynamic finite element analysis program you can use)

在Z2[X]中判断一个多项式是否本原多项式，并能对给定的多项式求逆。 (in Z2 [X] to judge whether a polynomial primitive polynomial, and the right to the inverse polynomials.)
