7.7.12.0. facSubWeyl
Procedure from library ncfactor.lib (see ncfactor_lib).

Usage:
facSubWeyl(h,x,y); h, X, D polynomials

Return:
list

Assume:
X and D are variables of a basering, which satisfy DX = XD +1.
That is, they generate the copy of the first Weyl algebra in a basering.
Moreover, h is a polynomial in X and D only.

Purpose:
compute factorizations of the polynomial, which depends on X and D.

Example:
