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