矩阵次对角化的进一步讨论

The Further Discussion On The Secondary Diagonalization of Matrix

本文根据矩阵特征根的属性给出了矩阵可次对角化的一个简明判定定理，并且给出了一类整数矩阵有理次对角化的方法。

This article presents a concise decision theorem that a matrix can be secondary diagonalized based on the characteristic of latent root of matrix, moveover it also presents the approach to the same kind of rational secondary diagonalixationof Matrix.
