----------------------------------------
Summary: elementwise power operator ^
Key: MAHOUT-1725
URL: https://issues.apache.org/jira/browse/MAHOUT-1725
Project: Mahout
Issue Type: Improvement
Reporter: Dmitriy Lyubimov
Assignee: Dmitriy Lyubimov
Fix For: 0.10.2
this is a power elementwise operation on in-core and out-of-core tensor types.
it is only defined on (tensor-type, Double) pair. This is consistent with R
caret operator.
e.g. computing distance between two points(vectors) x and y:
sqrt((x-y) ^= 2 sum)
Danger is that for integral types in Scala interpret this as exclusive or,
which is something completely different altogether .
