• Abstract

   

  The Pade approximation considered as interpolation problem by rational fractions is widely used to accelerate power series because to their accuracy. Its generalization in the orthogonal Chebyshev basis, a family of polynomials that presents a behaviour uniform, have been applied successfully in the resolution to various dependent problems of a variable. In this article, our approach aims to extend this generalization to functions of two variables. Numerical implementations are also presented.
