说明：  经典99行拓扑优化程序，采用Heaviside方程获得接近0-1离散解(The classical 99-line topology optimization program uses Heaviside equation to obtain nearly 0-1 discrete solution)

捷联惯性导航领域的姿态更新算法仿真，包括二子样、三子样和四子样的对比。(In the field of strapdown inertial navigation attitude updating algorithm simulation, including two sample, the third and the fourth kind of contrast.)

利用元胞自动机以及蒙特卡洛法模拟晶粒生长、凝固相变的一些源程序，以及对两种方法的一些简单文字介绍(The use of cellular automata and Monte Carlo simulation of grain growth, solidification phase change some of the source code, as well as two methods some simple text description)

有限体积法计算二维方腔流（含数值算法介绍及C++，Fortran源代码）(Calculation of two-dimensional cavity flow with finite volume method (including introduction of numerical algorithm and C++, Fortran source code))

feap 有限元程序，国外某大学的开源程序(feap finite element program)

全局牛顿-拉普森方法求解非线性方程组，自动搜索步长，进一步保证了程序的收敛(Global Newton-Raphson method for solving nonlinear equations. The steps can be found automatically. The convergence is better than the common Newton-raphson method.)

对简单开式网前推回代法计算潮流方便，已通过编译，有运行结果(back forward power flow)

压缩包包含三个文件： 全主元高斯-约当消元法程序AGJDN.m；基于全主元高斯-约当消元法的迭代求解病态矩阵方法AGJDNM.m；AGJDN.m的测试方程。 程序参考自：Fortran常用算法程序集（第二版） 徐世良编。AGJDN.m能求解部分病态矩阵，而AGJDNM.m对于我的测试矩阵效果不佳，但也一并上传，仅供参考。 错漏之处，还望指正。 (Gaussian-Jordan elimination base on all principal element.)
