MATLAB实现五子棋游戏（双人对战、可悔棋）

本文实例为大家分享了MATLAB实现五子棋游戏的具体代码，供大家参考，具体内容如下

程序介绍：

1、此游戏只可用于双人对战。

2、棋盘颜色、棋盘格数、棋子颜色等参数均可自由设置

3、鼠标点击非棋盘区域可悔棋。

一、游戏界面

二、主程序及函数

5、光标函数（由库函数改动而来）

%此函数为库函数的修改，仅将十字光标改为箭头光标，改动位置为第88行
function [out1,out2,out3] = ginput_pointer(arg1)
%GINPUT Graphical input from mouse.
%  [X,Y] = GINPUT(N) gets N points from the current axes and returns
%  the X- and Y-coordinates in length N vectors X and Y. The cursor
%  can be positioned using a mouse. Data points are entered by pressing
%  a mouse button or any key on the keyboard except carriage return,
%  which terminates the input before N points are entered.
%
%  [X,Y] = GINPUT gathers an unlimited number of points until the
%  return key is pressed.
%
%  [X,Y,BUTTON] = GINPUT(N) returns a third result, BUTTON, that
%  contains a vector of integers specifying which mouse button was
%  used (1,2,3 from left) or ASCII numbers if a key on the keyboard
%  was used.
%
%  Examples:
%    [x,y] = ginput;
%
%    [x,y] = ginput(5);
%
%    [x, y, button] = ginput(1);
%
%  See also GTEXT, WAITFORBUTTONPRESS.
