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