Is there a product function that works in the same way as diff?

I know that the diff function gives you an array with the difference of the array elements. Is there a function that works in the same manner but instead of difference gives me the product of every other element?

"...but instead of difference gives me the product of every other element?"

It is not clear what you mean by "every other element", but perhaps you mean either of these:

>> V = randi(9,1,8)
V =
   8   4   6   2   9   7   6   9
>> V(1:end-1).*V(2:end) % product of adjacent elements
ans =
   32   24   12   18   63   42   54
>> V(1:2:end).*V(2:2:end) % product of alternating elements
ans =
   32   12   63   54

Yes this is perfect. I wanted adjacent elements. Thanks!
