uart2.m

使用matlab编写的GUI

function varargout = uart2(varargin)
% UART2 M-file for uart2.fig
%      UART2, by itself, creates a new UART2 or raises the existing
%      singleton*.
%
%      H = UART2 returns the handle to a new UART2 or the handle to
%      the existing singleton*.
%
%      UART2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in UART2.M with the given input arguments.
%
%      UART2('Property','Value',...) creates a new UART2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before uart2_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to uart2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
