Hi!
I try to find out a solution by myself, but without result.
I have to call a singular function (vanishId) in the library
decodegb.lib. I write:
from sage.libs.singular.function import singular_function
from sage.libs.singular.function import lib as singular_lib
singular_lib('decodegb.lib')
singular_lib('matrix.lib')
vanish = singular_function('vanishId');
R=PolynomialRing(GF(11),['x%s'%p for p in range(0,17)],'degrevlex');
x=R.gens();
..
the main program write in sage
..
I have a list of lists, called points, and i eliminate duplicates
here:
provv=list();
for i in range(0,m-1):
cont=0;
for j in range(i+1,m-1):
if points[j]==points[i]:
j=m-1;
cont=1;
if cont==0:
provv.append(points[i]);
Now i have to convert sage list of lists into singular list of columns
vectors ( because vanishId takes a list of columns vectors)
presing=list();
for i in range (0,len(provv)):
presing.append(singular.matrix(1,17,provv[i]));
I set the ring to use ( also if i have declarated it before)
Rid = singular.ring(0, '(x(0..12))', 'dp')
I use it
Rid.set_ring();
I call the function
id=vanish(presing);
Traceback (click to the left of this block for traceback)
...
ValueError: Could not detect ring.

If i try to call vanishId like this:
id=vanish(presing,ring=R);

function.cpp:4877)
TypeError: unknown argument type '<class
'sage.interfaces.singular.SingularElement'>'
If i set the ring in "id=vanish(presing,ring=R);" like a singular ring
i recive:
TypeError: Argument 'ring' has incorrect type (expected
sage.rings.polynomial.multi_polynomial_libsingular.MPolynomialRing_libsingular,
got SingularElement)
I try everything! If someone know the truth post it!!!
Thanks
Best regards!
Andrea
