Matrix a*b in loop [message #89043]

Hi,
I have a simple question.

I have two matricies A (696 , 1523854 ) and B (1,696) Matrix .
I wish to have a matrix c whose each row is a product of rows elements of a and b i.e a*b

I can do it in a loop by saying a(:,i)*b but it takes a lot of time because I (~1523854 ) would be very large number. Is it possible to do it in one go.

Thanks
