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