说明： 上转型对象
1．实验目的
掌握上转型对象的使用。
2． 实验要求
要求有一个abstract类，类名为Employee，Employee的子类有YearWorker、MonthWorker和WeekWorker。YearWorker对象按年领取薪水，MonthWorker按月领取薪水，WeekWorker按周领取薪水。Employee有一个abstract方法：
public abstract earnings()
子类必须重写父类的earnings()方法，给出各自领取薪水的具体方式。
有一个Company类，该类用Employee数组作为成员，Employee数组的单元可以是YearWorker对象、MonthWorker对象或WeekWorker对象的上转型对象。程序能输出Company对象一年需支付的薪水总额。
(The transformation of the object 1. Purpose of the experiment used to grasp the transformation of the object. 2. Experiment requires a abstract class requirements, class named Employee, Employee of the child class has YearWorker, MonthWorker and WeekWorker. YearWorker object to receive annual salary, MonthWorker receive a monthly salary, WeekWorker receive weekly salary. Employee one abstract method: public abstract earnings () sub-class must override the parent class of earnings () method, given their own specific way of receiving pay. A Company class, such as members with an array of Employee, Employee of the array elements can be YearWorker object, MonthWorker object or objects on the transformation of objects WeekWorker. Company object program can output a year' s salary to be paid the total amount.)

bookMatlab
This book presents the MATLAB computer programming system as a problemsolving
tool for scientists and engineers who have no prior knowledge of computer
programming. It is based on a teach-yourself approach readers are frequently
invited to experiment for themselves in order to discover how particular constructs
work. The text was originally written as a companion to a hands-on course at the
University of Cape Town. Most of the students taking the course had little or no
computing experience and came from disadvantaged backgrounds. Consequently
the book assumes that readers have no knowledge of computing, unlike most
similar books on MATLAB.((2007 Elsevier)Essential Matlab for Engineers and Scientists(3rd Edition))

说明： 基于遗传算法的机械故障诊断，可以更好的对故障进行分离，使得结果更准确。使用该程序优化效率更高，相对于传统的优化算法，该算法运算速度更快。(Mechanical fault diagnosis based on genetic algorithms, you can better separate the fault, making the results more accurate. More efficient use of the optimization program, as opposed to traditional optimization algorithm computing faster.)
