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