非线性控制，在matlab中进行二阶对象的非线性仿真，研究其阶跃响应。(non-linear control)

说明：  图像处理，RS编码，纠错码这个单元对每个扰码后的传输数据帧,包括同 步字节进行截短的RS(204,188)编码.RS编码时, 在信息位前添加51字节的“0”再进入RS(255,239) 编码器,编码后再截去这些字节.RS(255,239)编码 (Image processing, RS coding, error correction code for each scrambling code of this unit after the transmission of data frames, including the sync byte truncated RS (204,188) code. RS encoding, the information bit before adding 51 bytes &quot 0 &quot and then enter the RS (255,239) encoder, encoding the bytes and then amputated. RS (255,239) coding)

功能：用BFGS算法求解无约束问题：min f(x) 输入：x0是初始点，fun,gfun分别是目标函数及其梯度； varargin是输入可变参数变量，简单调用bfgs时可以忽略它， 但是其他程序循环调用时将会发挥重要作用 输出：x,val分别是近似最优点和最优值，k是迭代次数。(Function: BFGS algorithm for unconstrained problem: min f (x) Input: X0 is the initial point, fun, gfun each objective function and its gradient varargin variable parameter is the input variable, it can be ignored when a simple call bfgs , but other programs will play an important role when the cycle is called output: x, val are approximate optimum and the optimal value, k is the number of iterations.)
