一、简介

四子棋是一款优秀的CONNECT 4游戏体验，玩家现在可以用全新方式玩这款老少皆宜的经典游戏。和对手见招拆招，第一个连起4个棋子的人即为获胜。

二、源代码

function connectfour(varargin)
%
% An implementation of the classic Connect Four by Milton Bradley.  Your
% goad is to arrange 4 chips in a row either vertically, horizontally, or
% diagonally before your opponent does.
%
% To play, simply click on the column in which you want to drop a peice.
% The computer will then automatically make its move.
%
% THE COMPUTER IS BEATABLE!  This is NOT the perfect Connect Four algorithm 
% that you may see on some websites.  The algorithm is good enough to win
% its fair number of matches.
%
% You can also click the "Demo" button to watch the computer play itself.
