sift匹配程序在matlab环境下的实现，包括特征提取与匹配(the sift match program realization in Matlab environment, including feature extraction and matching)

matlab的张量工具箱，方便使用，添加到库中就可以，可以方便实现关于张量等多维信息的计算(helpful for your tensor calculation)

说明：  EMD matlab实现代码，可以直接用。经验模态分解（Empirical Mode Decomposition，EMD）是由 Huang等人于1998年提出的一种针对非线性、非平稳信号的自适应信号分解算法。(Empirical Mode Decomposition (EMD) is an adaptive signal decomposition algorithm for non-linear and non-stationary signals proposed by Huang et al. in 1998.)

最新国外有关matlab的资料，是国内没有的，希望对大家的学习matlab有帮助。(Matlab latest information about the foreign, is not, we want to learn matlab help.)

二维FDTD程序，采用Mur吸收边界，实现了较好的吸收效果，可以用来与UPML吸收边界比较。(2D FDTD program, the Mur absorbing boundary to achieve a better absorption, can be used with UPML absorbing boundary.)

说明：  仿真螺旋交织器系统。要求将得到的整数序列放置在三个工作空间中并输出值。观察交织后数值的可视化变化规律。螺旋交织器模块参数：螺旋排列列数3；组的大小2；螺旋排列的跳步1；初始条件0。螺旋解交织器参数设置同螺旋交织器。斜坡函数模块参数：斜率1；开始时间0；初始输出1；矢量参数一维。缓存器参数：输出缓存长度6；缓存交叠0；初始条件0。仿真系统中的时延参数为7。(Simulation of helical interleaver system. Requirements will be placed in the three integer sequences and the output value of the workspace. Values observed after mixed visual variation. Helical interleaver module parameters: the number of columns 3, spirally arranged group size 2 spiral arrangement of jump 1 initial condition 0. Deinterleaving parameters set screw with helical interleaver. Ramp function module parameters: slope 1 start time 0 initial output 1 one-dimensional vector parameter. Buffer parameters: the length of the output buffer 6 cache overlap 0 initial condition 0. Delay parameter in the simulation system 7.)

C均值法的程序算法matlab 程序，本程序用MATLAB实现了聚类分析的功能，保存tex文件中，无数据(C-means algorithm matlab process procedures, the procedures used MATLAB implementation of the cluster analysis function, preservation of tex file, no data)

很好的Andriod 入门图书，值得一看。(Good Andriod entry books, worth a visit.)

This function takes a quantized analog signal and calculating the signal to quantization noise ratio (SNR)

说明：  超高频RFID读写器研究与设计 本课题以超高频RFID读写器硬件实现为主要本文设计RFID读写器硬件基带和射频部分的参数都可以满足要求，读写器可 以正常读、写符合15015000一6C或者 EpCglobalClasslGenZ协议的电子标签， 其上传速率可以达到640kbPs，配合上层的软件设计可以实现读写器考勤功能，经 过测试验证本系统可以长时间地稳定工作。 (UHF RFID reader research and design of this issue using the UHF RFID reader hardware designed in this paper as the main RFID reader hardware, baseband and RF part of the parameters are to meet the requirements of a normal reader can read, 15.015 million was in line with the agreement of a 6C or EpCglobalClasslGenZ electronic tags, its upload speeds can reach 640kbPs, with the top of the software design can be achieved reader attendance functionality, the system can be tested and verified for a long time stable jobs.)
