Summary: H20 implementation of AewUnaryFunc physical operator
Key: MAHOUT-1737
URL: https://issues.apache.org/jira/browse/MAHOUT-1737
Project: Mahout
Issue Type: Improvement

this physical operator allows to optimize elementwise expressions like

fused into one physical operator by logical optimizer.
This is an essential support.
