关于MATLAB写的一个贪吃蛇小游戏开发的源代码。(Writing about a MATLAB Snake game source code development.)

对于一幅输入图像，将产生一幅输出图像，输出图像的每个像素点的灰度值由输入像素点决定，将感兴趣特征的对比度扩展使之占据可显示灰度级的更大部分。使一输入图像转换为在每一灰度级上都有相同的像素点数，均衡化会减少灰度级数。大多数自然图像由于其灰度值分布集中在较窄的范围之内，引起图像细节不够清楚。采用直方图修正后可使图像的灰度间距拉大或使灰度均匀分布，从而增大了反差，使图像细节清楚，达到增强的目的。(For an input image, will produce an output image, the output image gray value of each pixel from the input pixel decided to expand interest in the contrast of features to make it account for more gray levels can be displayed most. Make an input image is converted to grayscale in each pixel have the same points, equalization will reduce the gray series. Most natural images because of their gray value distribution concentrated in a narrow range, causing the image detail is not clear enough. Make the image histogram revised by the gray space widening or so gray uniform distribution, thereby increasing the contrast between the image details clear objective to achieve enhanced.)

说明：  本源程序为matlab文件，实现最小生成树和关键路径的查找。(the source document for Matlab and achieve minimum spanning tree and find the critical path.)

自己编的5种调制信号仿真：CPFSK,FM,AM,QPSK,SSB，希望对大家有用(Their series of 5 modulation signal simulation: CPFSK, FM, AM, QPSK, SSB, we hope to be useful)

Digital signal processing using Matlab & wavelets

说明：  实现M序列的产生，用于产生M序列，它用在信号的加密，作为训练序列等(Realization of M sequence generation, used to produce M sequence, which used in signal encryption, such as the training sequence)

利用matlab实现数据模糊查询的功能，实现了在不精确数据中验证数据属于那个集合(Matlab fuzzy query data using the function )

成功实现计算elUpQJ算法的程序，本人测试已经通过，性能已基本达到elUpQJ算法的性能，需要MATLAB 2009b环境运行，如有问题，欢迎讨论 (The successful implementation of the program to calculate elUpQJ algorithm, I have passed the test, need MATLAB2009b operating environment, any questions, please contact me )

说明：  MATLAB 有哪些主要功能? 初学者应如何利用这一数学软件去解决自己的 问题？要解决这些问题，应该尽快熟悉一些常用命令，了解它们的功能和使用 格式。(What are the main functions of MATLAB? Beginners how to use the mathematical software to solve their own problems? To solve these problems, should be familiar with some commonly used command as soon as possible, understand their function and use format.)
