Lagrange interpolations using bivariate C-2 quintic supersplines on double Clough-Tocher refinements
In this paper, a local Lagrange interpolation set for a bivariate quintic superspline space defined on the triangulation (Delta) over bar (DCT) is constructed, where (Delta) over bar (DCT) can be gained through refining certain triangles in an arbitrary regular triangulation Delta by double Clough-Tocher refinements.
