G'day all.

Quoting Paul A Bristow <pbristow_at_[hidden]>:

I added the list of functions in TR1 to the wiki (SpecialFunctions).
Could you (or someone) please go through the list and add anything
that's already in Cephes? Then we can take a look at what's left.

Certainly not "too expensive" in terms of computing resources; as I
understand it, incomplete beta is no harder to compute than gamma.
Perhaps they meant too difficult to get a useful TR out that people
would actually be able to implement in reasonable time?
