四阶龙哥库塔法 Matlab函数代码 标准可用(RK-4 algorithm Four order Runge Kutta method Matlab function code standard available)

用于液体模拟，是研究cfd的一种新方法，称之为lattice boltzmann方法。本程序是d105模型的编码。这类编码网上很少，几近没有。如果哪们朋友有这方面的还希望能共用-for liquid simulation study cfd a new method, boltzmann called the lattice method. The procedure is d105 model coding. Few of these online coding, there was virtually no. If what they have friends in this area also hope to share

这是小时候的小孩玩过的比较经典的一款小游戏贪吃蛇，适合c++初学者借鉴-This is when the kids played a comparison of the classic Snake game for c++ beginners learn

纯CSS灰色的网站下拉菜单，可扩展性强，虽然没有过多美化，但是有些朋友就是喜欢这种简单的风格。本菜单在鼠标悬停于任意菜单项的时候，向下滑出二级子菜单，在火狐或chrome下也可以正常运行的。

1. 针对推挽结构MZ-LiNbO3调制器； （1）通过MATLAB编程画出输出电场、输出功率传递函数随外加波导两臂相位差的变化曲线； （2）确定相位调制器、强度调制器的偏置电压； （3）假设理想条件下强度调制器消光比为20dB，通过MATLAB编程画出消光比曲线随3dB耦合器分光比的变化。（分光比R=0.45:0.05:0.55）(1. For push-pull MZ-LiNbO3 modulator; (1) The curves of the output electric field and the output power transfer function with the phase difference between the two arms of the external waveguide are drawn by MATLAB programming. (2) Determine the bias voltage of phase modulator and intensity modulator; (3) Assuming that the extinction ratio of intensity modulator is 20 dB under ideal conditions, the extinction ratio curve of intensity modulator varies with the splitting ratio of 3dB coupler by MATLAB programming. (Spectrum ratio R = 0.45:0.05:0.55))
