% P12022248356 MATLAB code for p12022248356.fig
% P12022248356, by itself, creates a new P12022248356 or raises the existing
% singleton*.
%
% H = P12022248356 returns the handle to a new P12022248356 or the handle to
% the existing singleton*.
%
% P12022248356('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in P12022248356.M with the given input arguments.
%
% P12022248356('Property','Value',...) creates a new P12022248356 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before p12022248356_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to p12022248356_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

本文详细讨论了在程序设计中，对于Singleton模式的实现，显式地在某个地方进行初始化并使用GetInstance()方法获取实例的优势。这种做法有助于减少代码的不确定性，提高程序的可读性和维护性。
