ABSTRACT
They need only be pairwise distinct and noncollinear, i.e., not all lying on a single line. Consequently, we must also have n > 3. This situation arises far more frequently in practical applications than that of Part I. We look for a smooth interpolating function F = F{x,y) with
(6.2) where the z¿ are the values to be interpolated at the P¿.
