Subject [jira] [Commented] (MATH-1004) Inversion of diagonal matrix
Date Sat, 12 Oct 2013 11:14:42 GMT

    [ https://issues.apache.org/jira/browse/MATH-1004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13793335#comment-13793335
] 

Gilles commented on MATH-1004:
------------------------------

bq.  I would prefer adding it as MatrixUtils.inverse(DiagonalMatrix)

Why?
Note that the "blockInverse" operates on any base type that can provide an inverse. It's (sort-of)
higher-level. Here the implementation is specific to the actual type.
