Piecewise cubic interpolation of fuzzy data based on B-spline basis functions


Faculty of mathematical sciences, University of Tabriz, Tabriz, Iran


In this paper fuzzy piecewise cubic interpolation is constructed for fuzzy data based on B-spline basis functions. We add two new additional conditions which guarantee uniqueness of fuzzy B-spline interpolation.
Other conditions are imposed on the interpolation data to guarantee that the interpolation function to be a well-defined fuzzy function. Finally some examples are given to illustrate the proposed method.
