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 . -- This message was sent by Atlassian JIRA (v6.3.4#6332)
