Interpolation of fuzzy data by natural splines. (English) Zbl 0914.65001

Considering the Hausdorff metric, O. Kaleva [Fuzzy Sets Syst. 61, No. 1, 63-70 (1994; Zbl 0827.65007)] has shown the continuity of Lagrange type of fuzzy interpolation polynomial. The authors study here the interpolation of fuzzy data by fuzzy valued natural splines.
