>                 URL: https://issues.apache.org/jira/browse/SPARK-14697
>             Project: Spark
>          Issue Type: Bug
>          Components: MLlib
>    Affects Versions: 1.6.1
>            Reporter: Tamas Jambor
>            Priority: Minor
>
> When toArray is called from an mllib Densematrix, it calls the function from the superclass Matrix, where it creates a new array (and iterates through all the values).
> This is not necessary as values are stored in DenseMatrix, in exactly the format that this function would require. Why not just call that?
