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