克里金(Kriging)插值法又称空间自协方差最佳插值法，它是以南非矿业工程师D．G．Krige的名字命名的一种最优内插法。克里金法广泛地应用于地下水模拟、土壤制图等领域，是一种很有用的地质统计格网化方法。它首先考虑的是空间属性在空间位置上的变异分布．(Kringing smooth)

nondominated sorting genetic algorithms，nsga2的c语言源代码，比较好。(nondominated sorting genetic algorithms，nsga2 c-language source code better.)

基于matlab的约束非线性规划算法库，适于学习！(Matlab-based algorithm for the constrained nonlinear programming library, suitable for learning!)

说明：  所给的m文件中有详细的构造三对角分块矩阵的方法，而且构造的分块矩阵采用的是稀疏存储的方法，适用于大型三对角分块矩阵的构造(There are detailed methods to construct tridiagonal block matrix in the given m file, and the method of sparse storage is used to construct the block matrix, which is suitable for the construction of large tridiagonal block matrix.)

计算声发射时域信号特征值：裕值，振幅因子FK、fc，峭度，(Calculation of acoustic emission time-domain signal characteristic values: margin value, the amplitude factor FK, fc, kurtosis,)

矩阵计算，包括加减乘，反矩阵，python源码，可以直接使用(matrix calculation)

包络线去除完全用Excel函数写的包络线去除分析，仅实现了1850—2100nm的包络线去除，其他波段可自行扩展(Continuum Removal MATLAB Compiler 1. Prerequisites for Deployment . Verify the MATLAB Compiler Runtime (MCR) is installed and ensure you have installed version 7.13. . If the MCR is not installed, run MCRInstaller, located in: <mcr_root>* oolboxcompilerdeploywin32MCRInstaller.exe For more information on the MCR Installer, see the MATLAB Compiler documentation.)

说明：  求解黎曼问题格式Roe格式FORTRAN编程(Solution of Riemannian problem format roe format FORTRAN programming)
