2 Gabor函数结合代码分析：

二、源代码

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