#4951: expose Singular's numerical solver
-------------------------+--------------------------------------------------
Reporter: malb | Owner: jkantor
Type: enhancement | Status: new
Priority: minor | Milestone: sage-3.4
Component: numerical | Keywords:
-------------------------+--------------------------------------------------
This should be more Sage-ish:
{{{
sage: P.<x,y,z> = PolynomialRing(QQ)
sage: sage.rings.ideal.Katsura(P).dimension()
0
sage: I = sage.rings.ideal.Katsura(P)
sage: singular.lib("solve")
sage: singular.solve(I)
// characteristic : 0 (complex:8 digits, additional 8 digits)
// 1 parameter : i
// minpoly : (i^2+1)
// number of vars : 3
// block 1 : ordering lp
// : names x y z
// block 2 : ordering C
sage: singular.set_ring(_)
sage: singular("SOL")
