Vector Matrix multiplication (Row wise)
Mostra commenti meno recenti
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

L = L .* V;

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