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)".
