| Abstract: | A simple method of constructing low degree rational interpolation functions is meaningful in view of the practical application.A method of rational interpolating functions which can be operated easily is presented on the basis of the superposition thought and univariate vector Lagrange interpolation formula.The method is so flexible and simple that whatever types of rational interpolating functions which are needed can be constructed. |
