说明：  按照书本上教材编写的自适应中值滤波函数，很有参考价值(Materials prepared in accordance with the books adaptive median filtering function, a good reference)

fft自编源码，用于快速傅立叶变换的matlab程序(fft own source for the Fast Fourier Transform matlab procedures)

简要的介绍了在matlab中如何将gui转换为exe可执行文件(A brief introduction of how to convert the gui to exe executable file in matlab)

说明：  模拟蚂蚁和食蚁兽的生存规律。在20X20的网格世界里，每个生物每次可向四个方向移动（但不会移除网格边缘），食蚁兽会吃掉在他目标处的蚂蚁(The goal for this programming project is to create a simple 2D predator-prey simulation. In this simulation the prey are ants and the predators are doodlebugs. These critters live in a world composed of a 20x20 grid of cells. Only one critter may occupy a cell at a time. The grid is enclosed, so a critter is not allowed to move off the edges of the world. Time is simulated in time steps. Each critter performs some action every time step.)

词典编码LZW编解码的基本实现，包含LZW的编码和解码，实现了对lena图的编解码，用于数字图像处理。(The dictionary coding LZW the basic realization of the codec, including LZW encoding and decoding, the codec lena FIG for digital image processing.)

用Baum-Welch算法来迭代估计一个隐马尔科夫模型（HMM）的初始状态概率分布以及其状态转移概率矩阵。其中文件有mainfile_B_W.m为主函数，Baum_Welch.m为Baum-Welch算法迭代函数，Forward_variable.m与Backward_variable.m与Gamma_variable.m与Ksi_variable.m是需要计算的四种因子，B_pdf.m为混淆散射概率密度函数。(It s Baum-Welch algorithm for iteratively estimating the initial states probability distribution and state transition probability matrix. In the folder, "mainfile_B_W.m" is the main function, and "Baum_Welch.m" is the iteration Baum-Welch function. Also these four file "Forward_variable.m " "Backward_variable.m" "Gamma_variable.m" "Ksi_variable.m" are used for calculating crucial factors. "B_pdf.m" is the emission probability distrubution function.)

说明：  自己编制的傅立叶反变换MATLAB程序，有详细的注释，方便大家理解傅立叶反变换的意义。(Prepared by the Fourier inverse transform their own MATLAB programs, with detailed notes, to facilitate us to understand the significance of the Fourier inverse transform.)
