On the approximate factorization of 2-D polynomials
Zou Mou‐Yan, Rolf Unbehauen · IEEE Transactions on Acoustics Speech and Signal Processing · 1987
A method is presented for the approximate factorization of unfactorable bivariate polynomials. An efficient iterative algorithm is developed to minimize an appropriate criterion. The basic ideas can be easily extended to the case of polynomials in more than two independent variables. An example is presented to illustrate the utility of the method.
