这是一个用matlab编写的C4.5算法的实现(this is a classification of machine learing,C4.5,using matlab)

STL（Standard Template Library），即标准模板库，是一个具有工业强度的，高效的C++程序库。它被容纳于C++标准程序库（C++ Standard Library）中，是ANSI/ISO C++标准中最新的也是极具革命性的一部分。该库包含了诸多在计算机科学领域里所常用的基本数据结构和基本算法。为广大C++程序员们提供了一个可扩展的应用框架，高度体现了软件的可复用性。 (STL (Standard Template Library), which is a standard template library, with industrial strength, efficient C++ library. It is contained in the C++ standard library (C++ Standard Library), ANSI/ISO C++ standard is the latest in is also very part of a revolutionary. The library contains many in Computer Science in the field of common basic data structures and basic algorithms. Provides an extensible application framework for the majority of C++ programmers, highly reflects the software reusability.)

说明：  该系统为基于MATLAB平台的PCA的人脸识别系统，可识别ORL和YALE人脸库，方法实现统一，包括GUI界面。另外可二次开发成摄像头的实时人脸系统，识别出库外人脸，可做成门禁系统，考勤系统，打卡签到系统。实现登记出勤，报警等。 含论文，详细注释。(The system is a PCA face recognition system based on MATLAB platform. It can recognize ORL and yale face database. The method is unified, including GUI interface. In addition, it can be developed into a real-time face system of camera, which can recognize the face outside the warehouse, and can be made into access control system, attendance system, punch in system. Register attendance, alarm, etc. Including paper and detailed notes.)

文件是编辑好的m文件，在matlab环境下，放在根目录下可以直接调用，有稳定性的判据，和校正环节的整定等等。(functions)
