Comment(by was):
'''WARNING''' Extensive improvements on this code (which is really a
mess right now) are appearing in psage. See, e.g., the file lseries_nf.py
here:
http://code.google.com/p/purplesage/source/browse/#hg%2Fpsage%2Fellcurve%2Flseries
Having just written that code in psage (which involved going through the
code on this ticket), I would definitely not recommend including the
current code in Sage with a major rewrite. For example, code like this
in the patch:
{{{
s = 'v = %s; a(k)=if(k>%s,0,v[k]);'%( coeffs, upper_limit)
L.init_coeffs('a(k)', pari_precode = s)
}}}
is just masking confusion, since it's setting all Dirichlet coefficients
above a certain bound to 0, which is nonsense.
