双音多频编解码系统，用于产生双音多频信号，并由双音多频信号解码出对应的按键(DTMF codec systems, used to generate DTMF signal by the DTMF signal decoding keys corresponding)

我的毕业设计，用matlab仿真外弹道，在已有的外弹道模型下运用龙格库塔算法进行解算，最后做了相应的GUI界面！(I graduated from the design, simulation using matlab exterior ballistics, exterior ballistics in the existing model using Runge-Kutta algorithm solver, and finally made the corresponding GUI interface!)

用于迭代式搜索，和GA算法有相似之处，但收敛速度更快(for iterian searching)

在matlab环境下采用龙格库塔法解算的二维比例导引拦截仿真案例(proportional navigation trajectory )

这是一个指纹识别的matlab代码，用gabor滤波器处理的。(This is a fingerprint recognition matlab code processed using gabor filters.)

此程序是在MATLAB下进行图像的重构，先创建图像，然后计算投影，最后重构图像。(This procedure is carried out in MATLAB reconstructed image, to create an image, and then calculating the projection, the final reconstructed image.)

生成一个连通子图，适合图论学习，ACM竞赛以及网络学习(Generate a connected subgraph, graph theory is suitable to study, ACM contests, as well as e-learning)

自适应滤波器LMS算法的改进后的源程序的MATLAB程序(LMS adaptive filter algorithm improved source)

说明：  挠性转子的平衡原理是建立在弹性轴（梁）横向振动理论的基础上，其动平衡原理为：挠性转子在任意转速下回转时所呈现的动挠度曲线，是无穷多阶振型组成的空间曲线，其前三阶振型是主要成分，振幅较大，其他高阶振型成分振幅很小，可以忽略不计。(Flexible rotor balancing principle is based on the elastic axis (beam) on the basis of transverse vibration theory, the balancing principle is: flexible rotor turning at any speed when the deflection curve presented is composed of infinite number of vibration modes space curve, the first three modes is the main component, the larger the amplitude, the amplitude of the other components of higher modes is very small, can be ignored.)

This function implements brute force bactracking to solve the knapsack problem.
