             Summary: move RowMatrix.dspr to BLAS
                 Key: SPARK-10491
                 URL: https://issues.apache.org/jira/browse/SPARK-10491

          Issue Type: Improvement
          Components: MLlib
    Affects Versions: 1.6.0
            Reporter: Xiangrui Meng


We implemented dspr with sparse vector support in `RowMatrix`. This method is also used in WeightedLeastSquares and other places. It would be useful to move it to `linalg.BLAS`.
