Subject [jira] [Commented] (MATH-811) Improve event detection by selecting g function slope
Date Tue, 25 Sep 2012 07:55:07 GMT

    [ https://issues.apache.org/jira/browse/MATH-811?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13462529#comment-13462529

Dennis Hendriks commented on MATH-811:
--------------------------------------

bq. Ok, sorry for the tabs. Here is a new patch with spaces, but some files have been affected
by the autoformatting tool in Eclipse. 

The patch is already much shorter (and thus easier to process), but indeed there is still
some reformatting that obscures the actual changes. Ideally, the reformatting and the actual
changes would be done separately.

Anyway, I'm no expert on this issue, so I won't be reviewing it. Your proposed changes sound
interesting though!

> We would like to select g function slope in CommonsMath event detection feature.
> This would improve event detection for the final user (the possibility to ignore some
events, and less computation time) and also correct a bug found while using OREKIT (see https://www.orekit.org/forge/issues/104)
in our applications. 
> The modification consists in adding a method (getSlopeSelection() : int) in EventHandler,
and modifying one conditionnal in the method evaluateStep (class EventState). 
> We can provide modified code and unitary tests for this feature.
