Subject [jira] [Created] (LOGGING-150) Array2DRowMatrix#copySubMatrix could be improved for performance

Thomas Neidhart created LOGGING-150:
---------------------------------------

             Summary: Array2DRowMatrix#copySubMatrix could be improved for performance
                 Key: LOGGING-150
                 URL: https://issues.apache.org/jira/browse/LOGGING-150
             Project: Commons Logging
          Issue Type: Improvement
            Reporter: Thomas Neidhart
            Priority: Minor


Currently, the 2 copySubMatrix methods are inherited from AbstractRealMatrix where the copy
is done element by element. In the case of an Array2DRowMatrix this can be significantly improved
by using System.arraycopy similar as the setSubMatrix method already does.
