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