Approximate multidimensional polynomial factorization into general m — D polynomial factors

摘要

In this paper, a solution to the approximate factorization problem of the m — D polynomials is presented. More specifically, a non-factorizable multidimensional polynomial is approximately factorized into a product of general multidimensional polynomial factors in the sense of the least squares approach. The results are illustrated by means of a 2 — D numerical example.
