Abstract:
Numerically given functions with exponential asymptotic behavior are approximated by rational expressions. The numerators are obtained from the nodes of the functions, and the denominators are powers of polynomials, whose coefficients are obtained by expansion in orthogonal polynominals. Different weights are discussed for uniform absolute or relative errors. An iterative procedure is further described to improve the least-squares approximation to one of Chebyshev-type best fit.
