二、三阶可逆矩阵可以相似对角化的几何条件

Geometric Conditions under Which 2×2 and 3×3 Inverting Matrices Can Be Translated into Diagonal Forms

从几何的角度给出了特征值不含1的二、三阶可逆矩阵可以相似对角化的一个充分条件和二、三阶可逆矩阵可以相似对角化的一个充分必要条件.

In view of geometry, we give a sufficient condition of 2 × 2 and 3 × 3 inverting matrices for which 1 isn＇t eigenvalue can be translated into diagonal forms and a sufficient and necessary condition of 2× 2 and 3 × 3 inverting matrices can be translated into diagonal forms.
