Hi all,
I am currently working on a module where I need some "special" math
functions (elliptic integrals and Jacobi elliptic functions). This got
me thinking that there may be a place in the Numeric hierarchy for a
Special branch.
I think the only sane way to do this is with FFI, and I think the GNU
Scientific Library (GSL) is the best target for this. Some people may
have access to the IMSL or NAG libraries, but I doubt that most do. I
also believe that GSL is available for all of the targets currently
served by the various Haskell compilers, including Windows
The best way to attack this is probably to have a module for each group
of functions. So there would be Numeric.Special.Gamma,
Numeric.Special.Zeta, etc. The Haskell names would match the GSL names
minus the gsl_sf prefix.
Most (all?) of the functions are pure, and basically accept doubles or
ints as parameters and return a double. So, it's not a hard job, but
there are a zillion functions. I am willing to (slowly) tackle the job
since I already have it started.
Thoughts? Comments?
