I would like to do something like this Let say I have a matrix A of size 3x4

A =

     0     1     2     3
     1     0     0     0
     5     0     1     0
and a vector v of size 3x1
v =
     3
     5
     2
there is any way that I can produce an elementwise product as:
A v =
    3*[ 0     1     2     3]     0     3     6     9
    5*[ 1     0     0     0]=    5     0     0     0 
    2*[ 5     0     1     0]    10     0     2     0
without a loop?
