Is there an easier way of element-wise multiplying a vector, x, by each column in an array? Below I do it with a `for`

loop. I’ve tried using mapslices but I still need to broadcast x over each slice.

```
julia> x = [1;2;3]
3-element Array{Int64,1}:
1
2
3
julia> y = [1 2 3 4 5;6 7 8 9 10;11 12 13 14 15]
3×5 Array{Int64,2}:
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
julia> z = zeros(3,5)
3×5 Array{Float64,2}:
0.0 0.0 0.0 0.0 0.0
0.0 0.0 0.0 0.0 0.0
0.0 0.0 0.0 0.0 0.0
julia> for i=1:size(y,2);z[:,i] = x.*y[:,i];end
julia> z
3×5 Array{Float64,2}:
1.0 2.0 3.0 4.0 5.0
12.0 14.0 16.0 18.0 20.0
33.0 36.0 39.0 42.0 45.0
```
