矩阵按键程序，用的是C。本人还是学生，做得不好请大家多多指教(Matrix button procedure is used in C. I am still a student, doing a lot of bad advice please)

改进的burgers模型，非常适合学习UMAT的同志们学习，来自廖公云老师的《ABAQUS有限元软件在道路工程中的应用》(Improved burgers model is ideal for learning UMAT comrades learn from Liao Gongyun teacher "ABAQUS finite element software road works)

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.)

说明：  非常好的卡尔曼滤波学习程序。文章中有原题，有解题步骤，有实现程序。适合卡尔曼学习过程中的人。(Very good learning process Kalman filter. The article in the original title, there are problem-solving steps to achieve the procedure. Kalman learning process for people.)

不同接触模型下动力分析程序，对比了非线性Hertz及线性hertz接触下结果(Comparative analysis of the dynamic responses with different contact model )

说明：  含随机出题（四则运算）及其迭代程序、返回数组中最大子数组和及其迭代程序等。(Software class operations, including four operations and iterative procedure, returns an array of sub-arrays and the largest and Iterative procedures)

fortran code for LINEAR_WAVE PROPAGATION by upwind method.

加权总体最小二乘matlab工具箱，包含各种总体最小二乘算法的源代码(weighted total least squares toolbox)

最优潮流计算程序（使用电力系统专业，属于非线性规划问题）．(optimal power flow calculation procedure (using power systems professional, is Nonlinear Programming).)

以随机的中弱大气湍流为背景，可用于计算大气湍流下准直高斯光束的光强分布，光束扩展以及光束角漂移(The random weak atmospheric turbulence as the background can be used to calculate atmospheric turbulence of collimated Gaussian beam intensity distribution and beam propagation and beam angle drift)
