DTMF合成与识别MatlabGUI实例-DTMF.zip

%% GUI题头 function varargout = DTMF(varargin) % DTMF MATLAB code for DTMF.fig % DTMF, by itself, creates a new DTMF or raises the existing % singleton*. % % H = DTMF returns the handle to a new DTMF or the handle to % the existing singleton*. % % DTMF('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in DTMF.M with the given input arguments. % % DTMF('Property','Value',...) creates a new DTMF or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before DTMF_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to DTMF_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES % Edit the above text to modify the response to help DTMF % Last Modified by GUIDE v2.5 12-May-2013 12:25:02 % Begin initialization code - DO NOT EDIT gui_Singleton = 1; gui_State = struct('gui_Name', mfilename, ...
