Burgers方程作为流体计算中的经典模型方程之一，他的理论解作为验证求解格式的重要依据！(Burgers equation as a calculation of the classical fluid model equations, one of him as a validation of the theoretical solution to solve an important basis for the format!)

这是一个实现Levenberg-Marquardt算法的MATlAB代码，总共4个文件f.m产生目标评价函数，l_m_trust.m是进行L_M算法迭代处理，trtestlm.m是采用置信域方法决定更新参数和置信系数，而测试函数入口时test_lm.m，每个函数里面有详细的中文注释，希望能给你的工作带来帮助！(This is an implementation of Levenberg-Marquardt algorithm MATlAB code, generated a total of four documents fm objective evaluation function, l_m_trust.m is iterative processing algorithm for L_M, trtestlm.m Confidence region method is used decided to update the parameters and confidence coefficient and the test function entrance test_lm.m)

说明：  RS的编码就是计算信息码符多项式，除以校验码生成多项式之后的余数；rs编码的基本实现，包括add,mul函数等；(RS coding is to calculate the information symbol code polynomial, divided by the check code generator polynomial after the remainder rs basically coding, including add, mul function, etc. )

其基本思想是：采用信号与噪声的状态空间模型，利用前一时刻地估计值和现时刻的观测值来更新对状态变量的估计，求出现时刻的估计值。它适合于实时处理和计算机运算。 (The basic idea is: use of signal and noise state-space model, the estimated value of the previous time and are always observations to update the estimated state variables, find an estimate of time there. It is suitable for real-time processing and computing.)
