FFt例程，具有Pdf文档的具体说明过程。不错的啊！(FFt routines, Pdf file with the specified process. Good ah!)

自己编写的阵列信号DOA估计算法，包括MUSIC,root-MUSIC，esprit,F-sapes,MVDR.(I have written an array of signal DOA estimation algorithms, including MUSIC, root-MUSIC, esprit, F-sapes, MVDR.)

伪谱法求解程序，用于进行轨迹优化的有效方法-Gauss psedospectral method, used for trajectory optimization

说明：  本设计为基于MATLAB特征点匹配的指纹识别系统。带有一个GUI界面。主要对指纹图像进行三方面处理：图像预处理、特征提取和特征匹配。图像预处理包括四个步骤：图像分割、滤波增强、二值化、细化，对指纹图像进行预处理后，去除了原图像的冗余部分，方便后续的识别处理；特征提取主要是提取指纹图像细化后的端点和分叉点；特征匹配是利用两个指纹的图像进行特征点比较，来确定两幅图像是否来自于同一手指。(This design is a fingerprint recognition system based on MATLAB feature point matching. With a GUI interface. Fingerprint image is mainly processed in three aspects: image preprocessing, feature extraction and feature matching. Image preprocessing includes four steps: image segmentation, filter enhancement, binarization and thinning. After preprocessing the fingerprint image, the redundant part of the original image is removed to facilitate the subsequent identification processing; feature extraction is mainly to extract the refined endpoint and bifurcation point of fingerprint image; feature matching is to determine the two images by comparing the feature points of two fingerprint images Is it from the same finger.)

二维经验模态分解的一个程序，改进了插值算法。输入为图像灰度图(A program of two-dimensional empirical mode decomposition and improved interpolation algorithm. Enter the grayscale image)

一个老外写的802.11n无线局域网物理层（基带）simulink仿真模型，支持多种不同的速率。 关于模型的描述可以参见包内说明以及参考文献(Simulink model of 802.11n wireless LAN physical layer (baseband), supporting many diff rates. See the paper describing the model at: Wireless LAN Comes of Age: Undersanding the IEEE 802.11n Amendment by Thomas Paul and Tokunbo Ogunfunmi, IEEE Circuits and Systems Magazine, First quarter 2008, pp. 28-54. 2008. )

牛津大学开发的matconvnet工具包，可以生成vgg，alexnet等等模型，imagenet，mnist多种数据集可以跑(Oxford University developed matconvnet toolkit can generate vgg, alexnet etc. model, imagenet, mnist multiple data sets can be run)

matlab生成m序列的函数 原来那个效率太低，主要是因为实际应用并不需要生成太长的m序列，加入了需求长度，能有效减少运行时间。25级的移位寄存器，运行了一个小时都没有出来一周期，我仅仅需要三千bit而已。改进版：(matlab generate a function of the original m sequence that efficiency is too low, mainly because of the practical application does not require generation of long m sequences, joined the demand for length, can effectively reduce the running time. 25 of the shift register, run for an hour did not come out one cycle, I just need more than 3000 bit. Improved version:)
