哪位能帮我算一下下面矩阵的最大特征值以及该特征值对应的特征向量?非常非常的感谢!

[d,v]=eig([11/1.512.333
1.511.54
11/1.512.333
1/2.3331/41/2.3331])
d =
-0.4673 0.7071 -0.1864 - 0.2594i -0.1864 + 0.2594i
-0.7251 0.0000 0.8625 0.8625
-0.4673 -0.7071 -0.1864 - 0.2594i -0.1864 + 0.2594i
-0.1938 -0.0000 -0.0761 + 0.2149i -0.0761 - 0.2149i
v =
4.0022 0 0 0
0 0.0000 0 0
0 0 -0.0011 + 0.0946i 0
0 0 0 -0.0011 - 0.0946i
