本文主要是介绍【手写数字识别】基于BP神经网络手写数字识别matlab源码含GUI，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1 基于BP神经网络手写数字识别模型介绍

模型参考这里。

2 部分代码

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