> Implementing QR factorization in dml
> ------------------------------------
>
> Key: SYSTEMML-1161
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1161
> Project: SystemML
> Issue Type: New Feature
> Components: Algorithms
> Reporter: Imran Younus
> Priority: Minor
>
> The QR factorization can be used to solved the full-rank least square
> problem. It can also be used to do SVD decomposition.
> This will implement the QR factorization using the Block Recursive algorithm
> create by Elmroth and Gustavson. A simple representation of the algorithm is
> presented by Golub (Algorithm 5.2.3).
> Reference:
> "Applying recursion to serial and parallel QR factorization leads to better
