对图像加入白噪声干扰，用维特比译码进行去扰，分别用硬判决和软判决，显示出的图像可以看出不同的效果(White noise is added to the image, performed using Viterbi decoding descrambling, respectively, with the hard decision and soft decision, showing the different effects can be seen in the image)

说明：  通信原理中的数字调制方式与解调，包括了最常用的ask,psk,fsk的调制以及多种解调方式(the modulation and demodulation demo of ask, fsk ,dpsk and psk)

Ritz法解决-u +u=x 0<x<1，u(0)=0,u(1)=0的有限元边值问题。精确解为u(x)=1/(exp(1)-1/exp(1))*exp(-x)+1/(1/exp(1)-exp(1))*exp(x)+x，基函数为g(i)=sin(i*pi*x)(This matlab code is used to solve the boundary value problem of the differential equation: -u +u=x 0<x<1，u(0)=0,u(1)=0, where the accurate solution is : u(x)=1/(exp(1)-1/exp(1))*exp(-x)+1/(1/exp(1)-exp(1))*exp(x)+x)

实现数值分析中单纯形法改进方法的matlab代码，即改进单纯形法算法，能够实现大型稀疏矩阵的迭代，这是3/3..(Numerical analysis to achieve improved method simplex method matlab code that modified simplex method algorithm, to achieve large sparse matrix iteration, which is 3/3 ..)

由黄等提出了对EMD的改进方法EEMD，5条程序经过尝试均可使用(By Wong et proposed an improved method for EMD EEMD, 5 bar program has been tried and can be used)

说明：  这是一个基于最大信息判据的盲源分离算法程序，这个程序能很好的分离信号。(This is a criterion based on the maximum information algorithm for blind source separation procedures, which can be a very good signal separation.)

没会用，大家看看吧。工具箱这个是，我没太弄明白，也不是很会用，会用的真心麻烦您给个回复(never use it)

在matlab平台上对线极化、圆极化、椭圆极化电磁波的电场和磁场的情况进行仿真(On the platform of the situation matlab linear polarization, circular polarization, elliptical polarization of electromagnetic waves and magnetic field simulation)
