qt.m

结合Matlab的GUI和神经网络开发出来的界面

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