function varargout = OFDM_test(varargin) % OFDM_TEST MATLAB code for OFDM_test.fig % OFDM_TEST, by itself, creates a new OFDM_TEST or raises the existing % singleton*. % % H = OFDM_TEST returns the handle to a new OFDM_TEST or the handle to % the existing singleton*. % % OFDM_TEST('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in OFDM_TEST.M with the given input arguments. % % OFDM_TEST('Property','Value',...) creates a new OFDM_TEST or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before OFDM_test_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop.
