[jira] [Updated] (MAHOUT-1756) Missing +=: and *=: operators on vectors

     [ https://issues.apache.org/jira/browse/MAHOUT-1756?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dmitriy Lyubimov updated MAHOUT-1756:
-------------------------------------
    Description: Matrices support expressions like a *=: b (do elementwise a*b on b in-place) but vectors don't. sometimes it is highly desirable to do that type of expression, and for consistency, we should enable this for vectors too.
