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