lianxi02.m

用matlab来实现密码登陆窗口代码

function varargout = lianxi02(varargin)
% LIANXI02 M-file for lianxi02.fig
%      LIANXI02, by itself, creates a new LIANXI02 or raises the existing
%      singleton*.
%
%      H = LIANXI02 returns the handle to a new LIANXI02 or the handle to
%      the existing singleton*.
%
%      LIANXI02('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in LIANXI02.M with the given input arguments.
%
%      LIANXI02('Property','Value',...) creates a new LIANXI02 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before lianxi02_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to lianxi02_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
