[jira] Commented: (MATH-511) Class "Gaussian" can implement the "DifferentiableUnivariateRealFunction" interface

    [ https://issues.apache.org/jira/browse/MATH-511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12994577#comment-12994577 ] 

Gilles commented on MATH-511:
-----------------------------

I've implemented the "derivative" method in revision 1070698.
Please check it; there is an issue with NaN being generated but I'm not sure that the implemented fix is enough or all right in all cases.
