(x*y*z).sum()

"I have come to believe that the whole world is an enigma, a harmless enigm
I think I figured out: sum(X*Y*Z).
Never mind.

Hi All,
Given three vectors of the same lengths, X, Y, and Z, I am looking for
an efficient way to calculate the following:
sum(x[i]*y[i]*z[i], for i=1..n )
I am not sure if there is a vectorized way to do this.
Thanks,
Geoffrey
