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

% See also: GUIDE, GUIDATA, GUIHANDLES
