Edward J. Yoon commented on HAMA-156:
-------------------------------------
few bugs also fixed:
+ since we don't know a start index at DenseVector.add(), should check the
key/value.
+ DenseMatrix.get() should throw NullPointerException instead zero when it is
null
> Add SparseMatrix/Vector classes
