无标度网络生成程序。改程序可生成无标度的复杂网络，且很好展示了无标度网络的生成机理，对于初学者帮助很大。(Scale-free network generation program. Reform program will generate a complex network of scale-free, and good scale-free networks show the generation mechanism of great help for beginners.)

一个matlab的处理图像的函数的电子书，使用方便，可以搜索，非常实用(A matlab image processing function of the e-book, easy to use, you can search, very useful)

This demonstration is intended for people who know something about the theory of the discrete Fourier transform, and who would find it helpful to see some its properties demonstrated graphically, using a programming language. The demonstration shows the form of the Fourier components of a signal in 1-D and in 2-D, and shows how elementary filtering can be applied in the Fourier domain.

弹簧粒子模型定位算法，根据上海大学硕士论文编写。(Spring particle model localization algorithm，according to the Shanghai university master s thesis writing. )

说明：  支持向量机，用于分类，含训练集与测试集，用SVM进行多分类(Support Vector Machine (SVM), used for classification, including training set and test set, and multi-support vector machine (SVM))

MIT-BIH心电数据库中包含有大量的心电信号，用户可以直接下载这些信号用于信号分析，算法验证等。但是其数据存储格式复杂，只能用其提供的工具包进行读取，很不方便。本源码可以直接读取MIT-BIH中的format212和format16格式的心电数据，免去了学习其繁琐工具包的过程。(MIT-BIH ECG database contains a large number of ECG signals, users can directly download these signals used in signal analysis, verification algorithm. However, the complexity of its data storage format, can only provide a toolkit to read, very inconvenient. The source can be directly read the MIT-BIH in format212 and format16 ECG data format, which eliminates the cumbersome tool kit to learn their process.)
