简短的MATLAB语言，求出以V为水平初速度的物体下降弹道曲线方程及速度方程。以水平方向和竖直方向分解。(Short MATLAB, to find the initial velocity V as the level of objects down ballistic curve equation and rate equation. Horizontal and the vertical decomposition.)

说明：  离散系统的差分方程，该程序可以得出差分方程！结果挺好的！(equation)

C语言实现弗洛伊德路径搜索，同时为了提供接口，使用命令行方式给出原始矩阵地址，并且也已txt文本形式将结果保存。测试效果：一个需要在MATLAB中运行8秒的矩阵，在使用该程序时，总共只用了5秒（MATLAB初始化数据+调用该程序+该程序运行+返回至MATALB所用的时间）。而在MATLAB中使用该程序与调用函数相差不大。(C language Freud path search, and in order to provide an interface, use the command line gives the address of the original matrix, and also save results in text form txt. Test Results: A need to run 8 seconds in the MATLAB matrix, in the use of the program, a total of only 5 seconds (MATLAB initializing the program+ data+ call+ back to the program running time spent MATALB). In MATLAB, use the program with little difference between calling a function.)
