buck-boost升降压电路，输入电压为100v，输出电压为160v，采用PI控制调节系统占空比(boost-buck circuit, the input voltage is 100v, the output voltage of 160v, using PI duty cycle control regulation system)

一篇基于Matlab到OFDM研究开发的论文，有需要的朋友可以下载看看(An OFDM-based research and development of Matlab to the papers, a friend in need can be downloaded to see)

说明：  1， 自动去除导频，空子载波的simulink模块 2， 接下来是转二进制的模块（集成在解交织解卷积模型里，用一个Interger2Bit实现） 3， 然后是解交织解卷积模型—deconv. 负责解交织和解卷积 4， 再就是解RS解随机化模型—decode_new. 负责解RS解随机化 5， decode.m文件： 负责主程序的运行，实现参数的输入和修改，支持各种调制编码方式 (1, automatically remove the pilot, take advantage of the simulink Carrier Module 2, followed by a binary switch module (integrated in deinterleave deconvolution model, with a Interger2Bit achieve) 3, followed by deconvolution model deinterleave-deconv . responsible for reconciliation deinterleave convolution 4, Then solution RS solution model random-decode_new. responsible solution RS solution randomized 5, decode.m documents: the main program is responsible for the operation, to achieve input and modify parameters to support a variety of modulation encoding)

sift算法的详细应用笔记，对sift做了详细解释(sift algorithm detailed application notes, a detailed explanation of the sift)

where M is a model object (IDMODEL, IDPOLY, IDSS, IDFRD, or IDGREY). MAG is the magnitude of the response and PHASE is the phase (in degrees). W is the vector of frequencies for which the response is computed. These can be specified by [MAG,PHASE,W] = BODERESP(M,W). The frequency unit is angular frequency (rad/s or rad/M.TimeUnit). Only frequencies up to the Nyquist frequency are considered.

u can calculate DCT clc inp = imread( Im1.jpg ) inp1 = imread( Im2.jpg ) A = double(inp(:,:,1)) B = double(inp1(:,:,1)) A1=double(blkproc(A,[8 8], dct2 )) B1=double(blkproc(B,[8 8], dct2 )) [r,c] = size(A1) r1 = [] for i=1:r for j=1:c if A1(i,j) > B1(i,j) r1(i,j)=A1(i,j) else r1(i,j)=B1(i,j) end end end r1= double(r1(:,:,1)) C=blkproc(r1,[8 8], idct2 ) round(C) C1=idct2(r1) figure imshow(uint8(C)) figure imshow(uint8(C1)) imwrite(uint8(C), dct8x8min.jpg )

在matlab环境下面编程，最好使用2012版本及其以上，完成利用matlab软件提供的图像处理函数来完成图像匹配，3D重建的工作。最后的效果图很好，由于是利用matlab自带的图片，所以压缩文件中无图片，直接打开m文件就可以运行！(Below programming in matlab environment, it is best to use 2012 version and above, using matlab software provides complete image processing function to complete the image matching, 3D reconstruction work. The final renderings good, as is the use of matlab comes with a picture, so the compressed file without pictures, you can directly open the m-file to run!)
