结合Matlab的GUI和神经网络开发出来的界面

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