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