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)

经典非线性动力学模型，布鲁塞尔子模型，可直接运行，运算效率高。(nonlinear dynamics Brusselator model)

该软件主要应用是采用高斯正反算进行换带计算的。(The software application is used mainly Gaussian with positive and negative exchange balance calculation.)

用于拓展fluent磨损模型的UDF，采用tabakoff经验公式描述磨损量。(a udf to optimize erosion model in Fluent)

Una serie aritmetica en visual basic!!

这是用C++编写的 用高斯方法求解方程的方法 我想对与计算机数学的同学来说 可能会有用(It is written with C++ method for solving equations using Gaussian approach I want to mathematics and computer may be useful for the students)

说明：  最小二乘法拟合曲线的一个小程序，采用C++程序，(Least-squares fitting curve C++ program)

Orthogonal Polynomials Approximation 数值分析，计算正交基多项式的系数 (Given a function f and a set of m >0 distinct points . You are supposed to write a function to approximate f by an orthogonal polynomial using the exact function values at the given m points with a weight assigned to each point . The total error must be no larger than a given tolerance. Format of function int OPA( double (*f)(double t), int m, double x[], double w[], double c[], double*eps ) where the function pointer double (*f)(double t) defines the function f int m is the number of points double x[] contains points double w[] contains the values of a weight function at the given points x[] double c[] contains the coefficients of the approximation polynomial double*eps is passed into the function as the tolerance for the error, and is supposed to be returned as the value of error. The function OPA is supposed to return the degree of the approximation polynomial. Note: a constant Max_n is defined so that if the total error is still not small enough when n = Ma)
