应用matlab gui开发的信号分析小程序

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