Matlab functions for Spherical surface splines in tension

This project developed a Green's function solution for the case of spline interpolation under tension on a spherical surface. It extends Robert Parker's work on a minimum curvature spline [cf. Parker, R. L., 1994, Geophysical Inverse Theory, Princeton Univ. Press] for a sphere by adding tension.
