The Use of Array Algebra in Terrain Modeling Procedures.

摘要

Array algebra, a new technique that finds the least-squares fit of a model equation to a set of ordered data, is investigated as a possible replacement for the current conventional least-squares polynomial-fitting technique. Both techniques are described and analyzed within the context of their applicability to current terrain modeling procedures and are compared for computational efficiency. This analysis specifically considers increasing the number of model polynomial terms (up to 256 terms) and discusses the impact of array algebra upon future R and D activities involving these high order polynomials.
