non-self L functions and L functions of lattices

[Bill Allombert <allomber@math.u-bordeaux.fr>]

Dear PARI developers,

We added support for non-self-dual L functions and for L functions
of non-self dual lattices.

For example for D8:

D8={
[2,-1,0,0,0,0,0,0;
-1,2,-1,0,0,0,0,0;
0,-1,2,-1,0,0,0,0;
0,0,-1,2,-1,0,0,0;
0,0,0,-1,2,-1,0,0;
0,0,0,0,-1,2,-1,-1;
0,0,0,0,0,-1,2,0;
0,0,0,0,0,-1,0,2];
}
L=lfunqf(D8);
lfuncheckfeq(L)
%3 = -124
lfun(L,2)+2*Pi^2
%4 = 0.E-37

Cheers,
Bill.
