I checked different sizes of the sub-matrices and attached the code for
the evaluation to the bug report

Hi all,
I used the Apache Commons Math library in a project where I had to
create a lot of sub-matrices of Array2DRowRealMatrix. Analyzing the
runtime, I found that getSubMatrix could be implemented much more
efficient using System.arraycopy. You can find the patch that speeds-up
the runtime fo
