效果：
简单原理介绍：
1构造0,1矩阵作为每片拼图的透明度，可以构造出不规则形状的拼图(image函数有alphadata属性可以设置)
jigsawmask=zeros(101*5,101*5); jigsawmask(102:404,102:404)=1; [xmesh,ymesh]=meshgrid(1:101*5,1:101*5); dis1=sqrt((xmesh-51).^2+(ymesh-253).^2); dis2=sqrt((xmesh-505+50).^2+(ymesh-253).^2); dis3=sqrt((xmesh-253).^2+(ymesh-152).^2); dis4=sqrt((xmesh-253).^2+(ymesh-505+151).^2); bool1=dis1<=50; bool2=dis2<=50; bool3=dis3<=50; bool4=dis4<=50; jigsawmask(bool1)=1; jigsawmask(bool2)=1; jigsawmask(bool3)=0; jigsawmask(bool4)=0; jigsawmask(253-25:253+25,51:505-50)=1; jigsawmask(1:152,253-25:253+25)=0; jigsawmask(505-151:505,253-25:253+25)=0;
2为每片拼图块设置buttondownfcn属性，将其改造成按钮

运行m文件后选择一张接近方形的图片即可开始游戏
