Eliminate for loop: can this code be vectorized?

Hi all,
I am trying to optimize my code, my question is if it is possible to vectorize the following code:
for r = 1:2:(N-1)
U(r,1)=U(r,1)+ (1./K(r,r)).*(F(r,1)-K(r,:)*U(:,1));
end
where U and F are Nx1 vectors and K is a NxN matrix. This part of the code takes a considerable amount of time when N becomes large. Maybe someone has a suggestion on how to vectorize this part?
Thank you!
