摘要：

<正> Assume that a convergent matrix sequence{A_n}:A_n→A（n→∞）, A_n,A∈C3×3.We want to form a new matrix sequence {H_n}, derived from {A_n}, which has also A aslimit and whose convergence is faster than the of {A_n}. Three rational extrapolation meth-ods for accelerating the convergence of matrix sequences {A_n} are presented in this paper.The underlying methods are based on the generalized inverse for matrices which is useful
