说明:
改进的牛顿法求解:
方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*.
设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程
例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式.
方程中的系数a0由你得到的根p*来确定.
(improve Newton's method : Construction of the equation : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : Your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)

NLMS
若不希望用与估计输入信号矢量有关的相关矩阵来加快LMS算法的收敛速度,那么可用变步长方法来缩短其自适应收敛过程,其中一个主要的方法是归一化LMS算法(NLMS算法),变步长 的更新公式可写成
W(n+1)=w(n)+ e(n)x(n)
=w(n)+ (3.1)
式中, = e(n)x(n)表示滤波权矢量迭代更新的调整量。为了达到快速收敛的目的,必须合适的选择变步长 的值,一个可能策略是尽可能多地减少瞬时平方误差,即用瞬时平方误差作为均方误差的MSE简单估计,这也是LMS算法的基本思想。
(Want to estimate if the input signal vector and the relevant matrix to speed up the convergence rate of LMS algorithm, then the variable step size method can be used to shorten its adaptive convergence process, one of the main method is normalized LMS algorithm (NLMS algorithm) , variable step-size update formula can be written W (n+ 1) = w (n)+ e (n) x (n) = w (n)+ (3.1) where, = e (n) x (n) the right to express filter update vector iterative adjust the volume. In order to achieve the purpose of fast convergence, we must choose the appropriate value of variable step size, a possible strategy is as much as possible to reduce the instantaneous squared error, which uses the instantaneous squared error as the mean square error MSE of the simple estimate, which is the basic LMS algorithm思想.)

LINUX下的聊天小程序
在linux平台下,在同一局域网内实现聊天功能。整体框架主要分为服务端和客户端两个部分,设置好ip和端口号,在Linux下编译和调试两主大块程序,实现服务端和各个客户端的连接,然后以服务端为中转实现客户端之间的通信。采用linux流行的makefile编译,用gtk+进行界面的简单设计,以及Linux下的Socket进行数据通信编程,MySql进行数据的存储。最终实现带登陆和聊天界面,能进行注册、登陆、收发消息,查询聊天记录的一对一聊天工具。
