相似矩阵有相同的特征多项式，从而有相同的特征值。

Similar matrices have the same characteristic polynomial , thus they have the same eigenvalues .

相似矩阵有相同的特征多项式, 从而有相同的特征值.

Similar matrices have the same characteristic polynomial, thus they have the same eigenvalues.

基于差异—相似矩阵 ( dsm ) 的方法在很大程度上降低了文档空间的维度.

Difference - similitude Matrix - based ( DSM ) method reduces dimensionality to a great extend.
