摘　　要：讨论了一类基于Samelson逆的正矩阵值连分式的收敛性 ,建立了一种所谓的矩阵连分式的向后三项递推关系式 ,并利用此关系式研究了这种矩阵值连分式的渐近分式的性质以及给出了收敛的一些充分条件 。We consider a class of matrix valued continued fractions with positive elements, which are defined by the generalized(Samelson) inverse. We begin to give a so called backward three term recurrence algorithm for matrix valued continued fractions. By means of this relation, the properties of the convergents of matrix valued continued fractions are discussed. A few sufficient conditions of the convergence are obtained, and some of them are exact generalzation or improvement of the scalar results.
