基于DFT的瞬时测频算法，及插值算法，最后由图形表示测频结果。(Based on the Instantaneous Frequency Measurement DFT algorithm, and the interpolation algorithm, and finally by the graphical representation of frequency measurement results.)

读取BMP文件信息和显示，读取文件头信息，包括大小，长宽，水平和垂直分辨率，彩色数目，实际用到的彩色数目，关键颜色数目，压缩方式，每像素用到的bit数等(to read and display bmp file. output the header information, includnig file size, image width and height, horizontal and verticular resolution, number of color used and number of significant color, compression method, bit count per pixel etc.)

基于Matlab GUI的中重频PD雷达仿真系统，根据输入参数仿真，图形界面简单(MPRF PD radar simulation system based on Matlab GUI, according to the input parameters, simple graphical interface)

求解任意信道容量的迭代算法，求解方便而且实用。(Channel capacity to solve any of the iterative algorithm, solving convenient and practical.)

CMA算法实现自适应均衡器，对学习MATLAB软件，通信专业的人有用。(CMA adaptive equalizer algorithm, to learn MATLAB software, communications professionals who useful.)

模块化多电平仿真分析,可用于电力系统分析计算，高压直流仿真分析，毕业论文必备模型。(Modular multi-level simulation analysis, can be used for power system analysis and calculation, high voltage DC simulation analysis, the essential model of graduation thesis.)

基本粒子群优化算法Matlab源程序 网上找到的别人做的很简单的程序，写的很精练很工整，据说优化效果不是很理想，由于没有时间去做很多测试，所以就先摆在这里，但愿以后能用得上。 下面是主函数的源程序，优化函数则以m文件的形式放在fitness.m里面，对不同的优化函数只要修改fitness.m就可以了通用性很强。 (Particle Swarm Optimization Algorithm Matlab source code online to find others to do the procedure is very simple, very concise writing is very neat, is said to optimize the effect is not very satisfactory, because there is no time to do a lot of testing, so I have to put in here, I hope that can use later. The following is the main function of the source, optimizing the function form of the document on Zeyi m fitness.m inside, as long as the different optimization functions can modify the fitness.m highly generic.)

matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印，结果肉眼不易分辨出变化，不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过，如修改不严重，可提取隐藏信息，如果修改过多，则只能确定是否有修改，而不知道隐藏的信息是什么(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, such as modification is not serious, can extract hidden information, if too many modifications, you can only determine whether changes were needed, they do not know what information is hidden)
