modespage.m

产生IFF信号MODES询问及应答方式的GUI界面程序.

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