设是4的谱半径,且A是已知的,np(A)= A RC。本文给出了p(A)= ARC的一些充要条件。这些结果对于矩阵函数和线性迭代法的收敛性判据的某些应用是很方便的。
Let be the spectral radius of 4, and As is well knownp(A) = A RC . In this paper we give some sufficient and necessary conditions that p(A) = A RC . Our results are convenient for some applications in matrix functions and convergence criterion of linear iteration methods.
