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