说明：  利用matlab软件和fdtd方法来算三维结构的程序(Matlab software and the use of FDTD method to count the three-dimensional structure of the procedures)

this code is very helpfulful in understanding the basic sterps to create panorama

本附件包含在matlab环境下双谱分析源码的m文件，除了高阶谱，是用的比较广泛的一种。主要用于TDOA及弱信号检测等。可以动手下载后在matlab下运行之。和我前次发的高阶谱分析帖子一样，是要手动加入matlab高阶谱工具箱！ (This annex is included in the matlab environment bispectral analysis of source code of m documents, in addition to high-end spectrum, is widely used as a comparison. Mainly for TDOA and weak signal detection. Can begin download matlab running it. And my previous post issued order spectral analysis, is to manually add order spectrum matlab toolbox!)

图像的编解码程序，可以直接运行，并含有PSNR的对比(The encoding and decoding files which can run without modify, and we have comparison of PSNR)

可以用来进行电信预测的matlab代码，直接模仿就可以用了(Can be used for telecommunication prediction matlab code, you can use a direct imitation)

matlab二维拟合函数表达式 应用于lsqcurvefit(@myfun,a0,data,zdata) (非线性最小二乘法拟合)(curve fitting)

二维布朗运动的仿真，观察其分布特点，看某点做布朗运动后的运动点的分布（空间是矩形）(brown sim)

It is much easier to spot patterns in your data when you can associate an image with each datapoint. thumbnailScatter.m overlays an image thumbnail over each datapoint to help with visualization. For example, if you perform a principal components analysis and would like to plot PC1 vs PC2, use thumbnailScatter.m to see what properties each PC controls. Run demo_scatterThumbnail.m to see how it works. Test data are provided for the demo.

对振动信号进行时域分析，得到模态参数的方法。(The vibration signal in time domain analysis, modal parameters.)

P0301：数字图像矩阵数据的显示及其傅立叶变换 P0302：二维离散余弦变换的图像压缩，在MATLAB环境下均通过调试(P0301: digital image data display matrix and its Fourier transform P0302: Two-dimensional discrete cosine transform image compression, in the MATLAB environment through debugging)
