---------------------------------------
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.
