Hello all,I need to element-by-element multiply an nXk matrix A by an nX1 vector b, so that the result is that each row of A is multiplied by the corresponding row of b. This is on the inside loop of some intense calculations, so I'd like the best performance. Is C = A .* repmat(b,1,k) the best way to do this?
Thanks, Michael
