If we were to use a matrix for the output, then when we do
`approxSimilarityJoin` we would want to explode the output column by matrix
rows, assuming the matrix structure was:
````
| ---g1(x)---- |
| ---g2(x)---- |
| ... |
| ---gL(x)---- |
````
This is probably possible, but might be a bit awkward? `Array[Vector]`
might make it a bit easier.
