用matlab来实现密码登陆窗口代码

function varargout = a1(varargin)
% A1 M-file for a1.fig
%      A1, by itself, creates a new A1 or raises the existing
%      singleton*.
%
%      H = A1 returns the handle to a new A1 or the handle to
%      the existing singleton*.
%
%      A1('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in A1.M with the given input arguments.
%
%      A1('Property','Value',...) creates a new A1 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before a1_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to a1_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
