gskmadechar.m

基于人工神经网络的手写英文字母、数字图像识别的源程序代码。

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