复合材料损伤，复合材料层间分层，损伤，刚度退化、衰减(Composite damage, delamination of composite layers, damage, stiffness degradation, attenuation)

This is a simple mergesort code. It contains four directory. In the "lib" directory, there re two source code that can serve as timer and memory usage indicater. In the "src" directory, function "mergesort" can perform merge sort, while there s also a main function to execute it.

模糊控制的C语言实现，双输入单输出，采用查表法进行模糊推理，去模糊方法采用重心法，易于单片机实现(C language realization of fuzzy control, double input and single output, using look-up table method for fuzzy reasoning, using center of gravity method for deblurring, easy to realize by single chip computer)

分享一个外国人编写的FDTD程序,可以用来计算微带线和微带贴片天线,程序中采用的是均匀网格划分,但也可以在容易地在它基础上改写成非均匀网格.其边界条件与Sheen的程序不同,这里采用二阶技术.(Prepared to share a foreigner FDTD procedures, can be used to calculate the microstrip lines and microstrip patch antenna, the procedure used is uniform mesh, but can also easily rewrite it into the basis of non-uniform grid. its boundary conditions with different processes and Sheen, where second-order technology.)

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.)

Matlab是计算结构力学的好助手,计算结构力学(MATLAB is a good assistant in computational structural mechanics)

有效集法利用数学规划的对偶理论,将所求双层规划转化为一个下层只有一个无约束凸二次子规划的双层规划问题.然后根据两个双层规划的最优解和最优目标值之间的关系,提出一种简单有效的算法来解决非增值型凸二次双层规划问题.(Quadratic Bilevel Programming 　)

采用 Lax-Wendroff算法计算非粘Bergers方程(nonviscous Burgers equation, Lax-Wendroff method.)

说明：  用卡尔曼滤波方法对圆周运动进行预测的算法实现(Kalman filtering method using circular motion algorithm to predict)
