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

Usage:
facFirstWeyl(h); h a polynomial in the first Weyl algebra

Return:
list

Purpose:
compute all factorizations of a polynomial in the first Weyl algebra

Theory:
This function is a wrapper for facWeyl. It exists to make this library downward-compatible with older versions.

Assume:
basering is the first Weyl algebra

Note:
Every entry of the output list is a list with factors for one possible factorization. The first factor is always a constant (1, if no nontrivial constant could be excluded).

Example:
 
See also: facShift; facSubWeyl; testNCfac.
