some code for numerical analysis.The main goal is to provide insight into numerical analysis rather than merely to provide numerical recipes.

张正友的标定工具箱，直接运行会有错误，这是经过修改的工具箱，首先运行calib_gui,确认图像目录在current directory里，然后运行calib_gui_normal,出现图形界面，读取图像，进行标定(Zhang Zhengyou calibration kit, run directly there will be a mistake, this is the modified toolbox, first run calib_gui, confirm the image directory in the current directory, then run the calib_gui_normal, graphical interface, read the image, to carry on the calibration)

IIR FIR滤波器的实现，源码中给出了详细的关于IIR 和FIR滤波器在MATLAB实现的算法(IIR FIR)

Three-phase electric power is a common method of alternating-current electric power generation, transmission, and distribution.[1] It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. A three-phase system is usually more economical than an equivalent single-phase or two-phase system at the same voltage because it uses less conductor material to transmit electrical power.[2] The three-phase system was independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky and Nikola Tesla in the late 1880s.

该压缩包里有 MATLAB的许多源码，包括插值拟合。绘图等(MATLAB)

数字通信系统QAM仿真程序，基于MATLAB。(QAM digital communication system simulation program, based on MATLAB.)

根据图片手动选取像点，根据一定的组合顺序选择一定数量的像点，进行摄像机标定内外参数(According to the pictures manually select the image, based on a combination of a series of selecting a certain number of points, inner and outer parameters of camera calibration)

ofdm系统中功率自适应分配算法研究的matlab源代码（k＝20）(ofdm Power System Adaptive Algorithm for the distribution of the source code Matlab (k = 20))

说明：  简单实现了基于项目的协同过滤代码，MATLAB实现，需要解压(Simple implementation of project-based collaborative filtering code)

详细的介绍了MATLAB函数的功能,对初学者较有用!(MATLAB functions are introduced in detail the function more useful for beginners!)
