    [ https://issues.apache.org/jira/browse/MAHOUT-901?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13158478#comment-13158478 ] 

Sean Owen commented on MAHOUT-901:
----------------------------------

Sounds good, I generally trust you've investigated this and tested it -- any chance you have a unit test that just shows it outputs what you expect on a tiny data set? You can copy and paste others.

The code needs some formatting changes but I can do that. THe only line I question is the "catch (Exception)" bit -- should this not be replaced with bounds checking?
