"In the equation, both K and M contain wave vectors as complex matrices. The nodal displacement vector U has a non-zero solution condition and is not entirely zero. To obtain the functional relationship between wave vectors and frequencies, the determinant of equation (3) is equal to zero."
matlab求复数矩阵特征向量
可以使用`eig`函数来求解复数矩阵的特征向量。例如,对一个2x2的复数矩阵A求解特征向量:
```matlab
A = [1+i 2-3i; 4i 5];
[V,D] = eig(A);
```
其中,V是特征向量矩阵,D是特征值矩阵。注意,由于是复数矩阵,特征向量也是复数,因此V和D也是复数矩阵。可以通过`real`和`imag`函数来分别获取特征向量矩阵和特征值矩阵的实部和虚部。
