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