[jira] [Resolved] (MATH-726) Ridders derivative

     [ https://issues.apache.org/jira/browse/MATH-726?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gilles resolved MATH-726.
-------------------------

       Resolution: Incomplete
    Fix Version/s:     (was: 3.1)

The provided code was buggy.

Since the proposed API is not satisfying, and this does not seem to be high priority, it's better to revisit this once the basic interfaces have been set up.
