说明：  原创_proney算法，现代谱估计的一种，在信号处理中应用广泛(Original _proney algorithm, a kind of modern spectral estimation, is widely used in signal processing)

本代码用于模拟二维桁架结构在外载激励作用下、存在动力吸振器的情况下的响应情况，完全原创，只有一个m文件用于生成桁架振动动画的avi文件，其余三个函数用于辅助生成具体桁架结构的参数以及辅助计算。外载荷频率、动力吸振器固有频率可以通过改变代码中的变量来控制。(This code is used to simulate the two-dimensional truss structure as set out under the incentive, there are circumstances in response to the situation under dynamic vibration absorber, and completely original, only one file is used to generate m truss vibration animation avi files, the remaining three functions are used to assist generate specific parameters and supporting calculations truss structure. External load frequency, dynamic vibration absorber natural frequency can be controlled by changing the variables in the code.)

关于超声波倒车雷达测距的，对于初学matlab的同学会有帮助，基于matlab平台实现。( About ultrasonic parking radar ranging, Matlab for beginner students will help, Based on matlab platform.)

说明：  这是一个信赖域方法的程序，简单实用，对初学者非常有用(This is a trust region method procedures, simple, practical, very useful for beginners. )
