[Scilab-users] Can this loop be avoided?

Try this:
energy = ( log_data(2:$,1) - log_data(1:$-1,1) ).*log_data(1:$-1,2).*log_data(1:$-1,3);

Subject: [Scilab-users] Can this loop be avoided?

Hello All,
I have this for loop:
for i=1:size(log_data,'r')-1
    energy(i)=(log_data(i+1,1)-log_data(i,1))*log_data(i,2)*log_data(i,3);
end

The rows / loopsize are only a couple of thousands, so it is not that big of
deal, still I was wondering: It is possible to do this w/o a loop?

cheers
