I have two vector of matrix `AL = [A1, A2, ..., An]` and `wL = [w1, w2, ..., wn]`, I want to obtain the array of `[A1.*w1, ..., An.*wn]`, but `AL.* wL` gives me `[A1*w1, ..., An*wn]`. Is there any methods could make all the multiplicities into element-wise?

```julia
map(.*, AL, wL)

```

should do what you want.
