New description:
Existing code for nonsymmetric Macdonald polynomials in Sage (#2708) is in
sage.combinat.sf.ns_macdonald.py.
It uses the HHL algorithm and is limited to Type A. The patch at hand
extends this to arbitrary
Cartan types using Demazure-Lusztig operators.
This patch was written by Anne Schilling and Nicolas M. Thiery during the
ICERM Semester Program on "Automorphic Forms, Combinatorial Representation
Theory and Multiple Dirichlet Series" (January 28, 2013 - May 3, 2013)
with the help of Dan Bump, Ben Brubaker, Bogdan Ion, Dan Orr, Arun Ram,
Siddhartha Sahi, and Mark Shimozono. Special thanks go to Bogdan Ion and
Mark Shimozono for their patient explanations and hand computations to
check the code.
The patch in the combinat queue is trac_14102-nonsymmetric-
macdonald.patch.
