        摘要:SDSDD-矩陣是H-矩陣的一個(gè)子類,其逆的無窮范數(shù)在計(jì)算數(shù)學(xué)中有著重要的應(yīng)用價(jià)值.當(dāng)A是SDSDD-矩陣且B是一般矩陣時(shí),得到了‖A-1B‖的上界估計(jì)式.特別地,當(dāng)B為單位矩陣時(shí),給出了SDSDD-矩陣逆的無窮范數(shù)的上界和最小奇異值的下界,且新估計(jì)式只利用矩陣A的元素表示.數(shù)值算例表明了新估計(jì)式的有效性.

        關(guān)鍵詞:SDSDD-矩陣;H-矩陣;無窮范數(shù);上界;下界;奇異值

        Abstract: SDSDD-"matrices are a subclass of H-"matrices whose inverse infinite norm has important applications in computational mathematics. When A"is a SDSDD-"matrix and B"is a general matrix, the upper bound estimator for ‖A-1B‖"is obtained. In particular, when B"is an unit matrix, we present an upper bound for the infinite norm of inverse of SDSDD-"matrices and a lower bound for the minimum singular value of SDSDD-"matrices, and these new estimations are only based on the elements of the matrix. Numerical examples show the validity of the new estimators.

        Key words: SDSDD-"matrices; H-matrices; infinite norms; upper bound; lower bound; singular value
