利用行列式性质求矩阵的特征值

Getting Eigenvalues of Matrix by Character of Determinant

矩阵的特征值与矩阵元素之间存在着密切的关系,一些特殊的关系常常被人们所忽略,有效地利用这些关系可以很方便的得到一些结果.这里利用行列式的性质,得到某些矩阵的特征值.

The Eigenvalues of matrix and the matrix element are closely related.Some relations between them are ignored,though efficient results are conveniently got with the help of their relations.The paper tries to get some characteristic values of matrix by making good use of the character of determinant.
