Subject [jira] [Commented] (MAHOUT-756) VectorList (Matrix implementation) does maintain cardinality getters correctly
Date Sun, 10 Jul 2011 22:41:00 GMT

    [ https://issues.apache.org/jira/browse/MAHOUT-756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13062819#comment-13062819
] 

Lance Norskog commented on MAHOUT-756:
--------------------------------------

Perhaps like() and like(row, columns) should just make an empty VectorList? After all, like()
is not clone(). (Which VectorList does not implement and should.)

> VectorList (implements Matrix) is dynamically expandable, row-wise. There are three different
ways to query the size of a Matrix, and VectorList does not correctly supply these values.
