Vector Matrix multiplication (Row wise)

Hi, I need to multiply each row of very large matrix with a row of corresponding vector. I don't really want to use for loop for that, i.e.,

N=15000;
L=rand(N,N); V=rand(N,1);
for i=1:1:N
L(i,:)=V(i)*L(i,:);
end

is it possible to do this in vectorized way?

Thank you

Erdem

Answer 1

[Thorsten]

 L = L.*repmat(V, [1 N]);

[Kamuran]

Thank you

Answer 2

[Vladimir Kazei]

L = L .* V;

Answer 3

I'd suggest a faster version than the above methods:

 L = L .* v(:, ones(N,1));

Could you explain that why does this indexing trick work?

L = bsxfun(@times,L,V);
