This is a MATLAB implementation of the SIFT keypoint detector and descriptor (do_gaussian: generate Gaussian scale space of input image do_diffofg: generate Difference of Gaussian (DoG) scale space do_localmax: local extrema as the potential keypoints do_extrefine: refine the keypoints by discarding the ones with low contrast and along an edge do_orientation: compute the orientation of a support region of keypoint do_descriptor: compute the descriptor of a keypoint based on image gradients. do_match: match two images based on the nearest neighbor principle and spatial consistency. do_sift: generate the SIFT descriptors for a given input image. It basically s all the functions above. )

惯导轨迹仿真，对于初学惯导的人有很大的帮助(INS trajectory simulation, inertial navigation for beginners who have a lot of help)

说明：  可以将信号很好的进行LMD分解，很好用，自己试试看(The signal can be well decomposed into LMD)

说明：  如关键词，本人搭建的，在matlab2016b上测试。(For example, keywords, built by myself, are tested on MATLAB 2016b.)

本程序用于完成BPSK、QPSK、8PSK的调制仿真。并可任意扩展到MPSK和MQAM。程序分成三个部分：phase.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； model.m 为主程序，完成各种信号的基带星座图映射、脉冲成型和调制； command.m给出一个简单的频谱显示测试。(This procedure for the completion of BPSK, QPSK, 8PSK modulation simulation. Arbitrary and may be extended to MPSK and MQAM. Program is divided into three parts: phase.m symbol of the baseband shaping pulse sequences, optional rectangular pulse, the square root raised cosine pulse and raised cosine pulse model.m-based procedures, completed a variety of base-band signal constellation mapping , pulse shaping and modulation command.m given spectrum shows a simple test.)

说明：  简单的对图像进行锐化和平滑处理的函数，运行test函数即可，图像包含在文件中。(Simple sharpening and smoothing the image processing function, you can run the test function, the image contained in the document.)

算数编码，能够实现对图片或矩阵的算数编码程序。(some code of math)

是一本结合matlab学习数字信号处理得好书(Is a combination of digital signal matlab learning to deal with the book)

matlab /simulink 变频控制(matlab /simulink )

关于晶闸管控制串联电容器对系统暂态稳定性影响的matlab仿真。(Moeling and simulation of transience stability on a thyristor controlled series compensation. More comprehensive mathematical equations of TCSC circuit for any period (including the whole transient processfrom firing the thyristors to a steady state) and for the steady state relating to the voltages and currents of the capacitor,inductor and thyristor components are precisely developed by using Laplace transformation. And the accurate mathematicalrelationship between the fundamental impedance of TCSC and the firing angle of the thyristors is further derived by using Fourier analysis. Via the simulation, having a good understanding of the transience stability on a thyristor controlled series compensation. )
