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
