demo_detector.m

用matlab的gui编写的DTMF双音多频信号生成与检测的演示程序

function varargout = demo_detector(varargin)
%DEMO_DETECTOR M-file for demo_detector.fig
%      DEMO_DETECTOR, by itself, creates a new DEMO_DETECTOR or raises the existing
%      singleton*.
%
%      H = DEMO_DETECTOR returns the handle to a new DEMO_DETECTOR or the handle to
%      the existing singleton*.
%
%      DEMO_DETECTOR('Property','Value',...) creates a new DEMO_DETECTOR using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to demo_detector_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      DEMO_DETECTOR('CALLBACK') and DEMO_DETECTOR('CALLBACK',hObject,...) call the
%      local function named CALLBACK in DEMO_DETECTOR.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
