[jira] [Created] (SPARK-14697) mllib DenseMatrix toArray could use the internal values for the object

             Summary: mllib DenseMatrix toArray could use the internal values for the object
                 Key: SPARK-14697
                 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?
