Fast Outer Product call?

Hello,

Is there an efficient method that calculates the outer product of two one-dimensional arrays/vectors? I have looked at the TMatrix and TVector2 pages, but did not find anything like this. Is there one in STD?

Hi,

the GenVector class offers it:

ROOT::Math::XYZVector v1,v2
v1.Cross(v2)

or

Cheers,
