spectrally arbitrary pattern的意思|示意

In this paper, we present a new minimal spectrally arbitrary pattern by using the Nilpotent-Jacobian method.

作者在文中给出了一个新的极小谱任意符号模式。

I analyse some conclusions of spectrum arbitrary and give two sign patterns. then I prove two classes sign pattern matrix that are spectrally arbitrary using Nilpotent-Jacobi method.

分析了谱任意的相关结论并给出了两类符号模式，然后运用幂零雅可比方法证明了两类符号模式矩阵的谱任意性。

In the chapter 2, the author introduce two methods that method a sign pattern matrix is spectrally arbitrary, the structure method and Nilpotent-Jacobi method with examples.

第二章通过举例介绍了两种证明符号模式矩阵是谱任意的方法——构造法和幂零-雅可比方法。
