Subject [jira] [Commented] (MATH-1004) Inversion of diagonal matrix
Date Sun, 13 Oct 2013 15:49:42 GMT

    [ https://issues.apache.org/jira/browse/MATH-1004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13793687#comment-13793687
] 

Phil Steitz commented on MATH-1004:
-----------------------------------

+1 to Thomas' suggestion to have DiagonalMatrix directly implement inverse (with configurable
singularity threshold).

Probably should be a separate ticket, but +1 as well to MatrixUtils.inverse.  Question there
is what is best generic use decomp solver for inversion.
