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