I started working on this but then work flared up bug time.
I think I can return to this a week from now or maybe during this week.
Any news about this issue? If you do not expect to be able to work on
it, please let me know and I will.
Thanks,
Paolo.
Paolo,
I started on this and then changed my mind about the approach.
These functions obey a scaling law that allows you to scale the
arguments up by a factor and scale the function by an inverse factor.
I'm going to deploy this solution.
I also need to dig out the asymptotic forms of Bessel functions.
We'll have these in for 4.3 delivery for sure (sooner actually)
On a side note, I started work on accounting for where tr1::regex is in
the tr1 progress chart.
So unless someone else has done this I'll keep going on it. It
shouldn't take long and will help focus effort I think.
