非负矩阵分解的matlab代码

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