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:
- Implements the new algorithm by A. Heinle and V. Levandovskyy, see the thesis of A. Heinle
- 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).
