LEBFEK

LEBFEK: Matlab codes and data sets for bivariate Lebesgue and Fekete interpolation. In M. Briani, A. Sommariva, M. Vianello, Computing Fekete and Lebesgue points: simplex, square, disk we have described some algorithms for computing (quasi-)Lebesgue and (quasi-)Fekete points on the unit simplex, a square and on the unit disk. The respective codes and sets for these domains can be found in the links below. SIMPLEX; SQUARE; DISK.
