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