| Abstract: |
| Using B net method, a local Lagrange interpolation point set P of spline function space S31 (△CT) is constructed, where △CT is the Clough-Tocher refining triangulation, and a set of locally supported Lagrange basis is also given. |
| Key words: Lagrange interpolation point set Lagrange basis local support Clough-Tocher refinement |
