Non symmetric mac donald polynomials are also implemented in sage-combinat in a more general patch on multivariate polynomials. This is done by Lascoux's formula using divided differences, but as I am not a specialist I have not tested this part much.
You can see how the whole patch work on my website : http://igm.univ-mlv.fr/~pons/en/research.php 2012/8/30 bump <b...@match.stanford.edu>: > In addition to Macdonald polynomials there are the nonsymmetric Macdonald > polynomials > which for Type A are implemented in ns_macdonald.py by HHL > (Haglund-Haiman-Loehr) > combinatorial algorithm.
