matlab编写的实现surf的平台 老外的东西，可以进行验证(matlab prepared foreigner platform surf achieve things, you can verify)

FDTD仿真喇叭天线，能观察得到其电场在自由空间随时间的分布情况。(FDTD method is a time domain analysis.Here we first we design a wave-guide and there after we just increase its broad side.Our aim is to this simulation is plotting its electric field response with time and how will it response in outside free space. Here we just take 170 time steps one who can interested in antenna designing they can also plot the radiation pattern of this HORN antenna.Just take the field in the outside the mouth of HORN antenna and there do the simple formula to near filed far field transfer and measure it at your band of antenna.Best of LUCK all of you.)

找了很久的很不错kalmanfilter源代码，我比较了一下，是我找到的最好的。(a very good source code for kalmanfilter。)

模块化多电平逆变器的simulink仿真（7电平）(The simulation modular multilevel inverter (7 level))

说明：  是自适应滤波的一个源代码，用matlab编写，可以直接复制进行运行(Adaptive filtering is a source code, matlab written copy can be run)

有损和无损的图像压缩,DCT,哈夫曼编码(The lossy and lossless source coding in image processing, DCT and Huffman coding)

说明：  用不同模板对图像进行高斯噪声、椒盐噪声进行中值滤波均值滤波(Gaussian noise, salt and pepper noise are filtered by different templates, and mean filtering is used)

说明：  压缩感知是目前信号处理的新方法，本程序就是一个应用压缩感知的一个实例，有助于理解压缩感知。(Compressed sensing is a new method of signal processing, an application of this procedure is an example of compressed sensing to help understand the compressed sensing.)

surf特征点检测，并实现两幅图像特征点的匹配(surf feature point detection, and the two images matching feature points)

其中包括了matlab中最基本的算法院程序，对于编程有很大帮助(Matlab including the operator of the most basic court procedures, the program will be of great help)
