说明：  用MATLAB实现激光雷达的三维点云的重建。(Reconstruction of 3D point cloud with MATLAB)

说明：  交叉小波分析，用于气象、水文数据的分析等。(Cross-wavelet analysis for meteorology, hydrology, etc.)

模拟小孔或者圆形柱体结构的三维仿真图像，白光入射下的散射分析(Three-dimensional simulation image simulation holes or circular cylindrical structure, under incident white light scattering analysis)

dtmf signaling source code using matlab

chirp fourier transform 线性调频Z变换(CZT) 的matlab功能函数，该方法通过CZT变换获得精确的等价于离散傅里叶变换结果的间谐波信号的频率分布估计值,可以得到精确的各次谐波和间谐波参数,利用该函数相同采样频率下该方法的检测精度更高。(This routine allows the evaluation of the DFT over an arbitrary range of frequencies as its name implies this lets you zoom into a narrow portion of the spectrum.)

说明：  这就是陈建春的《用Visual C++开发GIS系统》的配套代码。 用来给初学者熟悉VC++图形编程很不错，我当初学MFC的时候就是照着这本书上手的。但作为一个GIS系统来说缺少一些必要的 要素，比如大数据量的管理、空间索引、符号化、投影等等等等等。以现在的眼光看来整个系统的架构设计也不是太好。 这本书再版后改名为《矢量图形系统开发与编程》，内容变化不大("using Visual C development of GIS systems" supporting code. For beginners to the VC familiar with graphical programming quite well, and I had the time to learn MFC is shining on this book in the business. But as a GIS systems lack the necessary elements, such as the large amount of data management, spatial indexing, symbols, such as projectors, etc.. Now the point of view of the entire system architecture design is not too good. This book reprinted later renamed as "vector graphics systems development and programming", little change)

说明：  在命令行输入%%滞回曲线 t0=0; tf=20; x0=[0 0 0] [t,x]=ode45('Lorenz',[t0 tf],x0); plot(x(:,1),x(:,3))，可得滞回曲线(Enter the%% hysteresis curve on the command line t0=0; tf=20; x0=[0 0 0] [t,x]=ode45('Lorenz',[t0 tf],x0); plot(x(:,1),x(:,3)))
