unit root test!!!!!!!!!!!!!!!!!!!!!including kinds of toolbox

modelling and simulation using matlab

基于牛顿法的配网潮流计算程序，采用改进牛顿法，对初学者有很大帮助(Calculation is based on Newton s method with network flow program, an improved Newton, a great help for beginners)

在线系统辨识资料以及辨识课件，讲解详细，有例题！还讲解了模型阶次辨识，有详细例题介绍！(Online system identification and identification of courseware, to explain in detail, with examples!)

本书附带光盘中包括了作者全书所有自己编写的算法对应的MATLAB的M文件。所有代码按照章节存放在各个文件夹下，如“第6章 无约束一维极值问题”文件夹下存放了本书第6章所有的算法程序代码。对于算法的程序代码，在光盘中存为同函数名的M文件，例如，minHJ.m表示用黄金分割法求解一维函数的极值的程序，依此类推。(The book contains CD-ROM, including all the M files of the MATLAB written by the author. All the code is stored in chapters under various folders, such as "Chapter 6 unconstrained one-dimensional extreme value problems" folder, all the algorithm code in Chapter 6 of this book. For the program code of the algorithm, the M file with the same function name is stored on the CD. For example, minHJ. M represents the program that uses golden section method to solve the extremum of one-dimensional function, and so on.)

it is about kmeans clustering

本程序可以用于解算各个扫面点的距离,以得到相应的座标点(compute the distance of scan point)
