增广最小二乘的递推算法对应的噪声模型为滑动平均噪声，扩充了参数向量和数据向量H（k）的维数，把噪声模型的辨识同时考虑进去。最小二乘法只能获得过程模型的参数估计，而增广最小二乘法同时又能获得噪声模型的参数估计，若噪声模型为平均滑动模型，，则只能用RELS算法才能获得无偏估计。当数据长度较大时，辨识精度低于极大似然法。(Augmented least squares of recursion algorithm corresponding noise model for moving average noise, expanded parameter vector and data vector H (k) of the dimension, the noise model identification and at the same time into consideration. Least square method can only obtain process model parameter estimation, and augmented least squares method at the same time can obtain noise model parameter estimation, if noise model for the average sliding model,, it can only use RELS algorithm to obtain unbiased estimation. When the data length is bigger, the identification accuracy is lower than maximum likelihood method.)

一个PSO算法历程，有详细的注释，及相关演示过程。采用了基本PSO、权重优化、最大速度法三种（去掉代码中的相关行的注释即可使用）。(PSO algorithm is a process, detailed notes, and related presentation process. With the basic PSO, weight optimization, the maximum speed law of three (remove the code related to the comment line can be used).)

说明：  两个用于图像处理的Matlab工具箱，OMPbox10和KSVDbox13，由于后者是要求安装前者的，所以就打包一起发上来了，下载一次就够了。(Two Matlab toolbox for image processing, OMPbox10 and KSVDbox13。 Since the latter requires the installation of the former, so packed together, so download once is OK。)

用matlab做的图像配准程序，可以实现图像配准(Image registration )

说明：  用于计算2D梁板壳的IGA程序,适用于IGA初学者(The MATLAB code for 2D modeling of beam, plane and membrane.)

用matlab实现二维情况下TM波的传播仿真，带有PML边界.很直观的！(realize the propogation of electromagnetic in TM mode under 2-D situation，with respect to the PML ABC.)

说明：  在vc++ 环境下对mapinfo的mif mid数据格式的文件进行操作（本程序附带部分数据方便大家学习）本程序不仅对道路、 等高线、 电力层、 独立地物、居民地、水系、图廓线等图层进行显示，而且实现了 缩放 漫游 开窗放大等基本的功能.是研究mapinfo数据格式的一个很好参考源码。 (In vc++ environment for mapinfo data format of the mif mid file operations (part of the data included in this program to facilitate them to learn) This program not only for the roads, contour lines, power level, independent surface features, the residents, the water system, figure profile and other layers to display, but also achieved roaming window zoom zoom and other basic functions. mapinfo data format is to study a good reference source.)
