摘要
利用复矩阵特征值模之平方的上界估计方法一舒尔不等式(schur's inequatlity)得出更加逼近的 结论:并由此结果给出奇异复矩阵特征值模之上界的一种估计方法.
In this paper,obtains a more close conclusion through Schur's inequality -a way estimating upper boundary of square of module of characteristic value of a complex matrix;as a result,gives a way estimating upper boundary of module of characteristic value of a complex singular matrix.
