说明：  包括我自己写的一些数值分析用到的函数 包括矩阵的LU分解的两种方法, Cholesky分解, 以及线性方程组的迭代解法中的雅克比, 高斯-赛德尔以及线性松弛法的函数(Including myself, used to write some of the numerical analysis functions, including matrix LU decomposition of two methods, Cholesky decomposition, and iterative solution of linear equations in the Jacobi, Gauss- Seidel and linear relaxation method function)

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.)

支持向量机作为统计学习理论的实现方法，能很好地解决非线性和高维数问题，克服了神经网络方法收敛慢、解不稳定、推广性差的缺点，近年来得到了广泛地研究，在模式识别、信号处理、控制、通讯等方面得到了广泛地应用。(Support Vector Machine as the implementation of statistical learning theory approach, can be a good solution to the nonlinear and high dimension problem, the neural network method to overcome the slow convergence, solution instability, bad promotion of sexual shortcomings, in recent years has been widely studied, at pattern recognition, signal processing, control, communications, etc. has been widely applied.)

混沌时间序列分析的瑞利熵的计算方法，可计算出序列中的renyi entropy。(renyi entropy)

说明：  应用fluent进行两相流的仿真，内容充实具体，简易使用，是进行两相流仿真的一个很好的算例。pdf文件。(Using fluent to simulate two-phase flow, the content is rich and specific, easy to use, is a good example of two-phase flow simulation)

对现在非常流行的非平行超平面进行编程，可用于twin svm等非平行问题。(Use for "Nonparallel Support Vector Machines")

用abaqus单元开发子程序uel生成弹簧单元。(User subroutine VUEL defining a three-dimensional spring element with degrees of freedom ordered in a nonstandard way)

适合于稀薄流动计算的气体动力学格式源码，该源码为xukun老是JCP论文中的算例一致(UGKS1D- shock structure calculation using Unified Gas-Kinetic Scheme)

线接触滑块润滑，基于有限差分法，采用的是中间差分的方法，求解油膜厚度(Line contact slider lubrication, based on the finite difference method, using an intermediate difference method for solving film thickness)

重力频率域位场延拓。将观测面的位场数据（a20_mag.gtd）向上延拓3.3m，之后与已知的理论值（a53_mag.grd）进行比较，计算其均方误差；反之，将观测面的位场数据（a53_mag.grd）向下延拓3.3m，之后与已知的理论值（a20_mag.grd）进行比较，计算其均方误差。(gravity frequency field extend)
