Just thought I might share this … even if its probably trivial for most of you.

Let assume you have a 3x3 matrix and vector of n length 3 vectors

```
K = rand(3,3)
V = [rand(3) for i=1:1000]
```

and you want to multiply K with each element of V

`K .* V`

or

`broadcast(*,K,V)`

will not work due to DimensionMismatch error

but this does work:

[K] .* V

broadcast(*,[K],V)

trivial but nice
