OFDM_GUI.m

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