calculator(varargin)

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