matlab code for GUI calculator

% Simple calculator for understanding of GUI

function varargout = calculator_2(varargin)

% CALCULATOR_2 MATLAB code for calculator_2.fig

% CALCULATOR_2, by itself, creates a new CALCULATOR_2 or raises the existing

% singleton*.

%

% H = CALCULATOR_2 returns the handle to a new CALCULATOR_2 or the handle to

% the existing singleton*.

%

% CALCULATOR_2('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in CALCULATOR_2.M with the given input arguments.

%

% CALCULATOR_2('Property','Value',...) creates a new CALCULATOR_2 or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before calculator_2_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to calculator_2_OpeningFcn via varargin.

%

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

% instance to run (singleton)".
