Algorithm

本程序是用数学方程试计算出一个点在一条线上的垂线坐标，并判断出在线内外，是测量中用的程序！(The test procedure is used to calculate the mathematical equation of a line a point in the vertical coordinate, and determine the line outside, the procedure used to measure!)

This program is used to find the union, intersection and exclusive OR for given two sorted arrays.

幻方 (magic cube )

将一些标准数值与非数值算法集中封装在几个DLL中,需要用时可在VB/Delphi/C#中分别调用,这里提供了3个小程序,分别用于线性方程组求根、计算行列式的值、矩阵求逆。(Some standard numerical and non-numerical algorithm focus on packaging in several DLL, it is necessary to use when in VB/Delphi/C# Call, respectively, this provides three small programs, respectively, for the roots of linear equations, calculation of the value of the determinant, matrix inversion.)

格子玻尔兹曼模型DnQm系列模型中应用较为广泛的D2Q7模型源代码，用于模拟流体的流动。(The D2Q7 model source code of the the Lattice Boltzmann the model DnQm series model is widely used to simulate fluid flow.)

说明：  研究舍入误差的例程，可以帮助初学计算方法的人。(Of rounding error in the routine that can help beginners who calculation.)

分数阶滑模工具箱，可用于解决阶次比较低的时候(fractional order sliding mode )

解线性方程组的迭代法 雅可比迭代、高斯—赛德尔迭代、超松弛迭代法 (Solving linear equations iterative method Jacobi iteration, Gauss- Seidel iteration SOR method)

说明：  经过优化的C代码实现的Gauss-Seidel 迭代算法(Optimized C code of the Gauss-Seidel iterative algorithm)

QR分解法是目前求一般矩阵全部特征值的最有效并广泛应用的方法，一般矩阵先经过正交相似变化成为Hessenberg矩阵，然后再应用QR方法求特征值和特征向量。它是将矩阵分解成一个正规正交矩阵Q与上三角形矩阵R，所以称为QR分解法,(QR decomposition )
