Use of boost to calculate the normal distribution and others

I did some tests and using boost for statistical functions has enormous advantages, as the implementations in Boost are optimal, use automatic promotion to improve te precision and are very well maintained respect to the native implementations.

I am adding a proof of concept for some functions (gamma and the normal distribution). The results are good but are not too different from the native versions.

This is unfinished work, I am not planning to work on this anymore but I leave the patches JIC someone wants to take over.

There seems to be little interest in this.

Pedro, we don't close thing just because they are not immediately integrated.  We have open issues, with patches attached, that are much older than yours.  

Be patient, please.

Let me clarify .. The patch was never ready for integration, it was just a propf of concept. Since no one is working on it, and I am too busy, I just want to drop it.

Is there someway to take it out of *my* bugs?

Pedro, you already said when you entered the issue:

"This is unfinished work, I am not planning to work on this anymore but I leave the patches JIC someone wants to take over."

So you already disowned the issue the day you entered it.  The bug is not yours.  Do not mark it "won't fix".  That is not your call.  

If you don't want notifications on this bug then all you need to do is stop changing it.
Comment 5 Rob Weir 2013-05-06 20:38:45 UTC
One other thing:  If you go to Preferences\Email Preferences, you can control in detail what kinds of notifications you receive from Bugzilla.

Withdraw patch.
Comment 7 Rob Weir 2013-05-07 18:40:19 UTC
Marked as a "medium" level issue, which might be suitable for a new developer after trying out some "easy" or "simple" bugs first.  

Please note that the attached patch is a "proof of concept" only.  It is *not* a patch ready for checking in.
