Re: [Quantlib-dev] bivariate student cdf?

[Michal K. <mic...@gm...>]

Dear Luigi,

please find the code attached.
(I have only limited experience with GitHub and, moreover, the code 
needs some QuantLib-ization before it can be added to the library..)

I have also included a short note with a link to the original paper and 
explaining some details of the implementation.

By the way, here is the link with the only other implementation of the 
bivariate student cdf, which I used for 
checking:http://www.math.wsu.edu/math/faculty/genz/software/software.html.
(They are based on the same paper, but the codes are GPL.)

I hope you find the code useful.

Michal
