1,0,0,0,0];

IDS?={'S1','S2','S3','S4','S5'};

bg?=?biograph(cm,IDS);

set(bg.Nodes,'Shape','circle');

set(bg,'layoutType','radial');

dolayout(bg);

bg.nodes(1).position?=?[100,300];

bg.nodes(5).position?=?[100,250];

bg.nodes(4).position?=?[100,200];

bg.nodes(3).position?=?[50?,200];

bg.nodes(2).position?=?[100,150];

dolayout(bg,'pathsonly',true);

view(bg);

輸出如下：
