统计一副图片中的直线数目，找到一幅图片中指定位置的直线，并进行标记。(The number of lines in the statistics in a picture, find the specified location in a picture of a straight line and mark.)

NMR and MRI simulation in matlab for chemical engineering applications

一个很好的算法，大家可以看看！很有用！ (A good algorithm, we can see!)

说明：  信号功率谱的AR模型估的MATLAB代码( PowerSpectrum Density Estimation based on AR mode. and MATLAB file )

主层次分析的过程及matlab的实现，有四个文件也就是四个函数(The main analytic hierarchy process and the realization of matlab four is four functions)

SFN MFN BER with Matlab

这一段源代码为瑞利衰落信道的实现，代码比较简单，适合初学者学习(This section of the source code for the realization of Rayleigh fading channel, the code is relatively simple, suitable for beginners to learn)

说明：  信号的时间宽度和频率带宽反映的是 、 围绕 和 的扩展程度，信号的带宽（ ）完全由幅度、幅度的导数及相位的导数所决定。称T和B分别为信号 的时宽和带宽，TB称为时宽－带宽积,。此程序用于计算信号的时间宽度和频率带宽。(Signal time width and frequency bandwidth of reflected that and it spreads around the signal bandwidth () completely by the magnitude, amplitude and phase derivative of the derivative of the decision. Called T and B respectively when the signal width and bandwidth, TB is called when the wide- bandwidth product. This program is used to calculate the width of the signal time and frequency bandwidth.)

arnold cat 映射实验，观察其迭代次数与置乱效果的关系，这是图像加密的典型算法(arnold cat mapping experiments to observe the number of iterations and the scrambling effect relationship, which is a typical image encryption algorithm)

鉴于本人去年7月份发布的《关于粗糙集和邻域粗糙集的基本理论和程序算例》其中有一些错误，可能给相关研究人员带来了误解，在此向大家道歉！ 同时在此资源中新增加了本人编写的邻域粗糙集的matlab计算程序，包括正域计算，约简计算，重要度计算，权重计算。 欢迎大家下载并交流学习！ 我所发布的两个版本的说明，以第二版本为主，第一个版本就不要下载了。 版权所有，除百度文库和中国程序员联合开发网上能下载到相关资源外，其他网站上的均为盗用。请尊重知识产权！(Given that I released last July, " the basic theory and procedures for rough sets and neighborhood rough set of examples," of which there are some errors, researchers may be brought to the relevant misunderstanding here to apologize! While a new addition to this resource I prepared matlab calculation procedures neighborhood rough set, including the positive domain calculation, reduction calculation, it is important calculation, the weight calculation.
