NumGens    --    number of generators

Syntax

NumGens(I: IDEAL): INT

Description

This function returns the number of generators ofI. 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
