Had to do a bit of looking around before saying anything but after some
looking and a bit of hacking a may say this:
* The GSL library contains what you are looking for.
* It is fairly simple to write a medium level binding to that library,
especially using GCC/GNAT.
I could post my small experiments if there is any interest.
