Arbitrary perturbation bounds on diagonalizable matrix 可对称化矩阵特征值的任意扰动
2.
The concept of a secondary diagonalizable ( sdiagonalizable ) matrix over quaternion field is defined , necessary and sufficient conditions for determining whether a matrix over quaternion field is a sdiagonalizable matrix are studied , and a method of finding sdiagonalizable matrices is given 摘要给出了四元数矩阵次对角化的定义，研究了一个四元数矩阵可次对角化的充要条件，并给出了使其次对角化的一个方法。
