求：（I-A）的逆矩阵
感谢万分！！

A=[0.134396,0.049018,0.010954,0.000633
0.153003,0.448744,0.202484,0.383519
0.061151,0.106204,0.206827,0.111386
0.023946,0.036817,0.039274,0.073269];
B=diag([1 1 1 1])-A;
inv(B)

答案：
1.1812 0.1182 0.0493 0.0557
0.4223 2.0212 0.5666 0.9048
0.1552 0.2932 1.3518 0.2839
0.0539 0.0958 0.0811 1.1285

LZ也不用“感谢万分”了。。。再加个几十分也就可以了。。。
