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