此工具箱是英国设菲尔德（Sheffield）大学编写的MATLAB遗传算法工具箱，是使用的最广泛的遗传工具箱之一。在《MATLAB 遗传算法工具箱及应用》作　者：雷英杰 出版社：西安电子科技大学出版社 这本书中重点介绍了此工具箱。( Sheffield genetic matlab toolbox)

本例用五点差分法求解一个二阶偏微分方程，其间用CG法处理，此实验可分别选取N=4，8，16，32(This example uses a five-point difference method for solving second order partial differential equations, during treatment with CG, were selected for this experiment can be N = 4,8,16,32)

这是一个信号处理很好例子，里面三角波，阶跃信号，以及方波信号的处理，有各种变换，同时也有gui方面的参考，代码能作参考，对小白很友好！(This is a good example of signal processing, triangle wave, step signal, and square wave signal processing, there are various transformations, but also GUI reference, code can be used for reference, very friendly to white!)

ClientGUI side for Chatroom, very awesome

雷达的恒虚警检测技术，二维cfar，采用十字形取数法(Radar CFAR detection technology, two-dimensional CFAR, using the cross number method)

matlab实现包络检波的一个小函数，以及2FSK信号生成和相干解调(A small function to achieve Envelope detection)

text to binary converter

采用eigen value来模拟各种衰落信道的源码程序，可以仿真瑞利衰落和AWGN叠加等等的情况。有详细注释。(Eigen value used to simulate a variety of fading channel the source program, you can simulation superimposed Rayleigh fading and AWGN and so on. Has detailed notes.)

用matlab编写的在png图像中隐藏并提取rgb图像和二值图像，注意隐藏的图像要小点，源图像png要大些(Png images using matlab hide and extract the rgb image and binary image, pay attention to the hidden image is smaller point source image png)

This code is used to simulation of bed load transport in two phase flow domain.
