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