Hi Anton,

Great work! It looks like you've got excellent programming skills
and a clear grasp of the problem domain.

As a next step, it might be interesting to investigate some
ranges of convergence in your Pade expansions for various types
such as float, double, long double, and multiprecision.

* What parameter ranges are convergent?

* How many terms do we need in the expansions for a given digit
range? (Don't be surprised if we need *lots* of terms for multiprecision
--- like hundreds of them.)

Please be sure to follow Boost's porogress on the application
process for GSoC.

It's just a little bit too early to apply to GSoC, but if Boost gets
accepted for GSoC, I look forward to your application.

Get back to me any time either on the list or via private
e-mail to discuss further details.

Keep up the good work!

Sincerely, Chris.

Hi all.

I just added a quick and naive implementation of
Pade approximation for 1f1 and 2f1
hypergeometric functions based on Luke's book.
You can find code here:

include/boost/math/special_functions/detail/hypergeometric_pfq_pade.hpp

I also want to thank Christopher Kormanyos for many advices and help.

Best regards, Anton.
