1. Multipoint Padé approximants used for piecewise rational interpolation and for interpolation to functions of Stieltjes' type
Sammanfattning : A multipoint Padë approximant, R, to a function of Stieltjes1 type is determined.The function R has numerator of degree n-l and denominator of degree n.The 2n interpolation points must belong to the region where f is analytic,and if one non-real point is amongst the interpolation points its complex-conjugated point must too.
