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