function varargout = guitest(varargin) % GUITEST M-file for guitest.fig % GUITEST, by itself, creates a new GUITEST or raises the existing % singleton*. % % H = GUITEST returns the handle to a new GUITEST or the handle to % the existing singleton*. % % GUITEST('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in GUITEST.M with the given input arguments. % % GUITEST('Property','Value',...) creates a new GUITEST or raises the % existing singleton*.
