摘要：

This paper provides a new method for approximating matrix-valued functions-square Pade approximation. Some computational methods of the approximants are given. For accelerating matrix sequences, a family of nonlinear extrapolation formulas based on the square Pade approximation is given, a convergence acceleration theorem is proved and numerical examples are presented.
