Subject [jira] [Commented] (MATH-884) "isSymmetric" in "MatrixUtils"
Date Mon, 29 Oct 2012 12:40:12 GMT

    [ https://issues.apache.org/jira/browse/MATH-884?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13485990#comment-13485990

Gilles commented on MATH-884:
-----------------------------

Supporting the raising of an exception makes it similar to other "check..." methods. (The
flag is not part of the public API.)
If there is a failed precondition and an exception is raised, it is probably nice to provide
the element's indices where the symmetry property is broken (the indices are arguments to
this exception's constructor). This cannot be done by just calling "isSymmetric" and then
raise the an exception if it returned false.

> I propose to move the method "isSymmetric" from "EigenDecomposition" to "MatrixUtils"
(package "o.a.c.m.linear").
