this code is for image forgery detection used to detect the changes made in the image

L-M(Levenberg—Marquardt)是一种非线性最优化里面最常用的方法之一，改方法能快速而准确的逼近收敛值。本文简述了改方法的操作原理和具体运用，如可以方便的用于有约束与无约束最优化的求解。(L- M (Levenberg- Marquardt) is a kind of nonlinear optimization inside one of the most commonly used method, change method can fast and accurate approximation convergence value.This paper briefly describes the operating principle of change method and concrete application, such as easy to solve constrained and unconstrained optimization.)

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.)
