function varargout = untitled1(varargin) %UNTITLED1 MATLAB code file for untitled1.fig % UNTITLED1, by itself, creates a new UNTITLED1 or raises the existing % singleton*. % % H = UNTITLED1 returns the handle to a new UNTITLED1 or the handle to % the existing singleton*. % % UNTITLED1('Property','Value',...) creates a new UNTITLED1 using the % given property value pairs. Unrecognized properties are passed via % varargin to untitled1_OpeningFcn. This calling syntax produces a % warning when there is an existing singleton*. % % UNTITLED1('CALLBACK') and UNTITLED1('CALLBACK',hObject,...) call the % local function named CALLBACK in UNTITLED1.M with the given input % arguments. % % *See GUI Options on GUIDE's Tools menu.
