这篇文章是盲信号处理，因为是英文文章，所以大家看内容就好了。(Principal component analysis (PCA) is a mainstay of modern data analysis- a black box that is widely used but poorly understood. The goal of this paper is to dispel the magic behind this black box. This tutorial focuses on building a solid intuition for how and why principal component analysis works furthermore, it crystallizes this knowledge by deriving from simple intuitions, the mathematics behind PCA . This tutorial does not shy away from explaining the ideas informally, nor does it shy away from the mathematics. The hope is that by addressing both aspects, readers of all levels will be able to gain a better understanding of PCA as well as the when, the how and the why of applying this technique.)

1. 定义一个抽象学生类CStudent，它具有公有成员函数Average()，该函数用于计算学生的平均分，函数为虚函数；定义一个文科学生类CStudentLiberalArts，它是类CStudent的派生类，并以公有方式派生，它具有的成员有： 1） 保存英语、政治、数学、地理和历史、美术成绩的整形成员变量； 2） 设置上述变量的公有成员函数； 3） 输出上述变量的公有成员函数； 4） 公有的成员函数Average()用于计算学生的平均分； 定义一个理科学生类CStudentScience，它是类CStudent的派生类，并以公有方式派生，它具有的成员为： 1） 保存英语、物理、数学、化学和计算机、程序设计成绩的整形成员变量； 2） 设置上述变量的公有成员函数； 3） 输出上述变量的公有成员函数； 4） 公有的成员函数Average()用于计算学生的平均分； 编写主函数，并测试以下内容： 1) 定义一个CStudent的指针数组pStu，数组长度为4； 2) 动态创建2个文科学生的对象，地址存于pStu数组的0-1个元素内； 3) 动态创建2个理科学生的对象，地址存于pStu数组的2-3个元素内； 4) 利用while循环调用数组里每个元素的计算平均成绩操作； 释放动态分配的空间，确保必要的析构函数能被调用。 (1 define an abstract class student CStudent, it has a public member function Average (), this function is used to calculate the student s average points function as virtual function definition of a liberal arts student class CStudentLiberalArts, it is the class CStudent derived class, and public be derived, which has members are: 1) Save English, shaping member variables politics, mathematics, geography and history, art achievements 2) Set the above variables public member function 3) public member function of the output of the variable 4) public member function Average () is used to calculate the average student s points The definition of a science student class CStudentScience, it is the class CStudent derived class, and public manner derived, which has members as follows: 1) Save English, physics, mathematics, chemistry and computer programming achievement shaping member variables 2) Set the above variables public member function 3) public member function of t)
