NumGens

number of generators

Syntax 
NumGens(I: IDEAL): INT

Description
This function returns the number of generators of I . This is more direct, therefore efficient, than writing len(gens(I)) , because it does not create the temporary list gens(I) .

Example 
/**/  use R ::= QQ[x,y,z];
/**/  I := ideal(indets(R))^40;
/**/  NumGens(I);
861
