摘要
讨论了扰动H-矩阵行列式的估计问题,得到了扰动H-矩阵行列式相对误差的上、下界的一个估计式,把扰动M-矩阵行列式估计的相关结果推广到了扰动H-矩阵。
Estimation of determinant for perturbed H-matrices is discussed, a estimation formula of upper bound and lower bound of the relative errors on determinant of perturbed H-matrix is obtained and the mail result on M-matrices in [2] is generalized to H-matrices.
