THE COMPUTER EXPLORATIONS TOOLBOX --------------------------------- This directory contains the Computer Explorations Toolbox, which is the set of M-files and data files which accompany the textbook "Computer Explorations in Signals and Systems using MATLAB" by John Buck, Michael Daniel, and Andrew Singer, Prentice Hall.

说明：  这个模型可以在MATLAB中，为数据库的进入，提供时间倒数，以防止过多地试密码，从而提高系统的保密性( TIMEOUT = LOGINTIMEOUT(FIRSTARG,SECONDARG) returns the current value of time allowed for a connection to a database to be successful. FIRSTARG, an optional argument, is a string that specifies the JDBC driver to be used establishing the database connection. SECONDARG, an optional argument, is an integer that specifies the length of time the driver will attempt to make a connection to a database. If FIRSTARG is not specified then the default JDBC/ODBC bridge is used to establish the connection to the database. If function is used without arguments then the current time out value is returned. )

可以方便的求极限，对于matlab的初学者有用。(limitation)

典型信号的调制解调以及性能分析，毕业设计要求，绝对好用(Typical signal modulation and demodulation, and performance analysis, graduation requirements, absolutely easy to use)

认知无线电的频谱检测算法的MATLAB实现，完整版。(Cognitive radio spectrum detection algorithm of the MATLAB realization of the full version.)

OFDM 系統加AWGN的性能模擬,訊號的Mapper使用QPSK,Guard interval 取資料的符元是1/4，輸出信號與原始信號比較出錯誤率。(Plus AWGN performance of OFDM system simulation, signal Mapper use of QPSK, Guard interval operators access to information, the yuan is 1/4, the output signal and compare the original signal error rate.)

说明：  我个人认为比较好的matlab 怎么应用到c上去的文档，介绍给大家，希望能喜欢。(I personally think how good Matlab Application c boost to the document, introduced to the hope of love.)

本程序为边界元的原程序，可用来求解2D位势问题，附数据文件(the procedures for the original boundary element procedures can be used to solve 2D Potential problems with data files)

这是一种基于密度的聚类分析算法，可以发现任意形状的簇，可以发现噪声点。(This is a density-based clustering analysis algorithm can find clusters of arbitrary shape can be found noise points.)

指纹识别技术，包含指纹识别MATLAB源程序，功能强大(The fingerprint identification technology, fingerprint contains MATLAB source, the function is strong)
