Bar Code 2.rar_bar code

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