说明：  《有限元方法编程（第三版）》随书源码。 采用 Fortran 90 编制，近 400 个计算子程序。在 64 位机器上编译通过，并运行正确。( Finite Element Method Programming (Third Edition) With the book source. The preparation of the use of Fortran 90, nearly 400 calculation subroutine. 64 machines in the compiler is passed, and run correctly.)

there is an other java project in eclipse explaine how to code a simple calculator with a motor class

C写的填充算法源码 算法可是在编程中可是非常重要的 大家可以参考一下这个代码,学习一下算法(C padding algorithm source code algorithm but in programming is very important, you can refer to this code, learn the algorithm)

使用Matlab软件计算Normal Copula,Student t Copula,Clayton Copula,Gumbel Copula的程序(Calculated Normal Copula, Student t Copula, Clayton Copula, Gumbel Copula using Matlab software )

二层地质模型波场模拟,用有限差分进行波场的模拟,充分利用多波多分量地震记录，以及各向异性方面的独特信息，可有效地减少 纵波勘探的多解性，定量地描述裂缝储层，改善某些纵波资料成像不好地区的构造 成像。这样可获得比纵波分辨率高的多波剖面，从而有利于研究小幅度构造、断层、 裂缝裂隙等复杂地质现象，对油气勘探与开发具有现实意义和实用价值(Two-layer geological model wave field simulation, using finite difference wave field simulation to make full use of multi-wave multi-component seismic records, and the anisotropy of the unique information can be effective in reducing the P-wave exploration, multi-solution and quantitatively describe the crack reservoir to improve the poor image of some P-wave data area structure imaging. This availability of higher resolution than the longitudinal wave of multi-wave profile, thus contributing to the small amplitude structures, faults, cracks, fissures and other complex geological phenomena, for oil and gas exploration and development of practical significance and practical value)

能够实现二维边界造波，且自带消波，能够较好地模拟波浪荷载。(with a prgram of eliminating wave,it can be used to achieve boundry wave.)

浸入边界法（Immersed Boundary Method）的一个示例程序。包括说明文档。(A code using the IBM (Immersed Boundary Method ) . And the help documention is included .)

复杂网络的结构检测室近几年的研究热点，目前最快的算法是标签传播！(Community detection is hot topic in recent years. The most fast algorithm for community detection is Label Propagation Algorithm(LPA),and this is the program!)

说明：  这是数值分析的一些作业实验，文件中有详细的文档对理论，实验和算法的说明，用于病态方程组求解的源代码(This is the numerical analysis of the experimental operation, the paper detailed documentation of theory, experiment and the algorithm shows that morbid equation for solving the source code)
