SB.RandomPoly
This function returns a random polynomial of a given subalgebra.
Syntax
SB.RandomPoly(S: TAGGED(<quotes>$apcocoa/sagbi.Subalgebra</quotes>), d: INT): POLY
Description
This function computes a random polynomial of degree d from S.
Warning: Very inefficient!
@param S A subalgebra
@param d An integer
@return A random polynomial of degree d in the subalgebra S
Example
Use P ::= QQ[x,y,z]; S := SB.Subalgebra(CurrentRing,[x^2,y^2,x+y]); SB.RandomPoly(S,3); -- -2*x^3 -10*x^2*y +3*x*y^2 +11*y^3 +2*x^2 +4*x*y -4*y^2 +3*x +3*y -- (if you just started ApCoCoA)
