求助：关于MATLAB的问题

我最近在看《通信天线建模与MATLAB仿真分析》这本书，第7章有个多带天线Sierpinski蝴蝶结天线的仿真，可是我用书中配套的MATLAB程序仿真出的天线模型却与书上不一样（莫名其妙少了2个小三角），看了半天也看不出程序哪里出了问题，希望有人能帮帮我，提前谢谢了！

上面的程序调用下面的函数
function [CatX, CatY, T1X, T1Y, T2X, T2Y, T3X, T3Y]=divider(InpX, InpY, TAN);
h=max(InpY)-min(InpY);
CenterX=0.5*(min(InpX)+max(InpX));
CenterY=0.5*(min(InpY)+max(InpY));
CatX=[-h/2*TAN 0 h/2*TAN]'+CenterX;
CatY=[ 0 h/2 0]'+CenterY;
T1X=[-h*TAN -h/2*TAN 0]'+CenterX;
T1Y=[h/2 0 h/2]'+CenterY;
T2X=[0 h/2*TAN h*TAN]'+CenterX;
T2Y=[h/2 0 h/2]'+CenterY;
T3X=[-h/2*TAN 0 h/2*TAN]'+CenterX;
T3Y=[0 -h/2 0]'+CenterY;
