testgui3.m

用matlab的GUI做的一个数字信号处理系统

function varargout = testGUI3(varargin)
% TESTGUI3 M-file for testGUI3.fig
%      TESTGUI3, by itself, creates a new TESTGUI3 or raises the existing
%      singleton*.
%
%      H = TESTGUI3 returns the handle to a new TESTGUI3 or the handle to
%      the existing singleton*.
%
%      TESTGUI3('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TESTGUI3.M with the given input arguments.
%
%      TESTGUI3('Property','Value',...) creates a new TESTGUI3 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before testGUI3_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to testGUI3_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
