用matlab的GUI做的一个数字信号处理系统

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