1 A1 LISTING PROGRAM 1. Form Cover function varargout = cover(varargin) COVER MATLAB code for cover.fig COVER, by itself, creates a new COVER or raises the existing singleton*. H = COVER returns the handle to a new COVER or the handle to the existing singleton*. COVER('CALLBACK',hObject,eventData,handles,...) calls the local function named CALLBACK in COVER.M with the given input arguments. COVER('Property','Value',...) creates a new COVER or raises the existing singleton*. Starting from the left, property value pairs are applied to the GUI before cover_openingfcn gets called. An unrecognized property name or invalid value makes property application stop. All inputs are passed to cover_openingfcn via varargin. *See GUI Options on GUIDE's Tools menu.
