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