RE: [Lapackpp-devel] Cross Product

[Jacob \(Jack\) G. <jg...@cs...>]

That's the one.

I implemented it myself, since it's not used in any loops, I don't really
need the optimization of lapack.  However, if it is implemented in lapack, I
think we should have a wrapper for lapack++.  I think it's used often enough
in the computer vision world.

Dear Jack,

Do you mean the cross product as explained here 
http://mathworld.wolfram.com/CrossProduct.html which is a function of 
R^3 x R^3 -> R^3
? No, this function is not available. From what I remember, the cross 
product has so limited use in numerics that the numerical people 
wouldn't implement such a function. But you are really looking for this 
function?
