Smooth Surface Approximation by a Local Method of Interpolation at Scattered Points.

摘要

This report describes a computer program which constructs a surface passing through a set of data points (x sub k,y sub k,f sub k), k = 1,...,n. It is based on previous work, but uses a somewhat different approach which takes advantage of the nature of the approximations used and incorporates experience gained in the ensuing period. The surfaces are defined for all (x,y) points and have continuous second partial derivatives.
