function varargout = gui1(varargin) % GUI1 MATLAB code for gui1.fig % GUI1, by itself, creates a new GUI1 or raises the existing % singleton*. % % H = GUI1 returns the handle to a new GUI1 or the handle to % the existing singleton*. % % GUI1('CALLBACK',hObject,eventData,handles,…) calls the local % function named CALLBACK in GUI1.M with the given input arguments. % % GUI1('Property','Value',…) creates a new GUI1 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before gui1_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to gui1_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES
