说明：  这是用MATLAB 编写的有关城市旅游商问题的最新程序，挺有效。(MATLAB prepared by the city tourism to the latest procedures, they are effective.)

说明：  陀螺运动的仿真程序，动力学仿真和动画同时表示 陀螺在重力下以适当的初始速度落地的仿真结果(Gyro movement simulation program, dynamic simulation and animation at the same time that the top of the gravity of the initial velocity to the appropriate landing simulation results)

物质点法c语言程序，可实现三维泰勒杆问题的仿真分析。(Material point method C language program)

熟悉matlab的人都会很清楚matlab中的feval()函数没法对匿名函数进行运算，当然更不可能执行当前路径之外或者说搜索路径之外的函数。还有eval只能执行字符串命令。 9 q2 u8 e" L& Y, E Z8 {然而evalf解决了上面的所有问题 (Matlab person familiar with the very clear matlab in feval () function can not be anonymous function of computing, of course, impossible to implement outside of the current path or the path outside the search function. There can only run eval command string. 9 q2 u8 e L )

this is partial code for paper "A Robust Wavelet-Based Watermarking Algorithm Using Edge Detection"

主要用于校正图像的畸变，用matlab编写的，很实用(Mainly used to correct image distortion, written with matlab, very practical)
