极坐标3d画图程序，功能很强大，自己看帮助吧(POLARPLOT3D Plot a 3D surface from polar coordinate data)

效果很好的直线提取算法，抗噪声能力很好，希望对大家有用(Uses the method of Video Compass to get long， straight edges)

这种双线性插值的matlab源代码,学生需要可以下载使用(This kind of bilinear interpolation of matlab source code, students in need can be used to download )

Tic-Tac-ToeThis is a very user friendly tic-tac-toe game with three different difficulty levels. Download the zip file tictactoe.zip then extract the contents in to a folder and in MATLAB run tictactoe.m by typing tictactoe at the command line. You can play against a friend or the computer. The difficulty level can be adjusted in the file menu. The expert level promises to give even the best player a challenge!(This is a very user friendly tic-tac-toe game with three different difficulty levels.

暂时只支持jpeg2000支持的 cdf97 和spline53 可以这样来测试： x=imread( E:studyjpeg2000imageslena.tif ) ％ see the decomposition coefficients y=wavelift(x, 1, spl53 ) using spline 5/3 wavelet figure subplot(1,2,1) imshow(x) subplot(1,2,2) imshow(mat2gray(y)) ％ see the reconstruction precision yy=wavelift(x, 5) using cdf 9/7 wavelet ix=wavelift(yy,-5) inverse sum(sum((double(x)-ix).^2)) (only temporary support jpeg2000 support cdf97 and spline53 this can be measured Examination : x = imread (E : study jpeg2000 images lena.tif)% see the d ecomposition coefficients wavelift y = (x, 1, spl53) using spline 5/3 wavelet figure subplot (1,2,1) imshow (x) subplot (1,2, 2) imshow (mat2gray (y))% see the reconstructi on precision wavelift yy = (x, 5) using cdf 9/7 wavelet ix = wavelift (yy.-5) inverse sum (sum ((double (x)- ix). ^ 2)

Wilson法求解动力方程，可以画出节点的位移响应(Wilson method for solving dynamic equations, you can draw the node displacement response)

This library contains helper functions to read image frames into matlab from Video file using DirectShow. This library has borrowed codes from Ashwin Thangali s "DirectShow (DirectX) based AVI file reader", and it can read multiple video formats besides avi. Features: a) can read frames from rmvb, avi, etc. b) handles most codecs installed on the system d) its implementation is only based on the IMediaDet interface -- Depending on your Matlab version, the .mexw32 files may need to be renamed as .dll -- The library usage is as follows, [avi_hdl, avi_inf] = dxVideoOpen(avi_filename) pixmap = dxVideoReadMex(avi_hdl, frame_num) img = reshape(pixmap,[avi_inf.Height,avi_inf.Width,3]) dxVideoCloseMex(avi_hdl) -- recompile the library I have compiled the code with the DirectShow lib in Microsoft DirectX 9.0 SDK Update (December 2004) -- known limitation a)only works for windows :( b)may be slow for big image frames and some codecs.
