一、案例简介

1 借用小波包分解和小波能量熵函数；
2 西储大学轴承故障数据；
3 提取小波能量方便快捷；

二、部分源代码

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

% --- Executes just before wavlet_package_energy_GUI is made visible.
function wavlet_package_energy_GUI_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to wavlet_package_energy_GUI (see VARARGIN)

% Choose default command line output for wavlet_package_energy_GUI
handles.output = hObject;

% Update handles structure

% UIWAIT makes wavlet_package_energy_GUI wait for user response (see UIRESUME)
% uiwait(handles.figure1);


% --- Outputs from this function are returned to the command line.
function varargout = wavlet_package_energy_GUI_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure

% --- Executes on selection change in listbox1.
function listbox1_Callback(hObject, eventdata, handles)
% hObject    handle to listbox1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hints: contents = cellstr(get(hObject,'String')) returns listbox1 contents as cell array
%        contentsget(hObject,'Value') returns selected item from listbox1


% --- Executes during object creation, after setting all properties.
function listbox1_CreateFcn(hObject, eventdata, handles)
% hObject    handle to listbox1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called

% Hint: listbox controls usually have a white background on Windows.
%       See ISPC and COMPUTER.
