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