The secon part of student work about using matlab for imege prossesing.

BP神经网络模型，用于根据反馈信息，调整，以达到最优值(BP neural network model for feedback adjustments to achieve the optimal value)

算法的研究基于matlab模糊神经网络的预测算法-嘉陵江水质评价(A fuzzy neural network prediction algorithm )

用matlab的gui编写的DTMF双音多频信号生成与检测的演示程序，运行方法见readme，希望能对大家有所帮助。(Matlab by the gui prepared DTMF DTMF signal generation and detection demo program, run method see readme, for all of us hope to be helpful.)

I wrote this program for coloring any map with only 4 colors. Input for it is an bitmap file with 24 bit colors (must gray/scale). Output is a bitmap which is colored with maximum 4 colors.

数值计算，求解函数最优化的一个工具，是一个库函数，(Numerical calculation, to solve the function optimization of a tool, a library function,)

说明：  MATLAB常用函数，它拥有详细的分类，希望都大家有所帮助！(MATLAB commonly used function, which has a detailed classification, hopes to help all of you!)

the code of eigenface

这是好的LBG程序，对初学的人有相当大的帮助，一看就会懂很多。(this is good LBG programme, it is useful for you.)

扩展的空间调制，打破了传统空间调制技术发送天线数目必须是2的幂数的限制，提高了频谱利用率。(The extented spatial modulation breaks the constraint of the traditional spatial modulation in which the number of the transmit antenna must be a power of 2 enchancing the spectrum efficiency.)
