xj_2.m

应用matlab gui开发的信号分析小程序

function varargout = xj_2(varargin)
% XJ_2 M-file for xj_2.fig
%      XJ_2, by itself, creates a new XJ_2 or raises the existing
%      singleton*.
%
%      H = XJ_2 returns the handle to a new XJ_2 or the handle to
%      the existing singleton*.
%
%      XJ_2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in XJ_2.M with the given input arguments.
%
%      XJ_2('Property','Value',...) creates a new XJ_2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before xj_2_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to xj_2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
