kuandai.asv

通信系统的GUI设计

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