Changes in 0.14:

Here you can find my Scientfic Computing with Math::GSL Podcast from PDX.pm.( Stream, Download) In the talk I compare PDL and Math::GSL, talk about the Google Summer of Code 2008, and show off some of the subsystems that are currently working. I field some questions from the audience about whether Math::GSL does symbolic computing or parrallelized/vectorized computing (it doesn't, at least yet) and how exactly I turn Perl subroutine references into C function pointers. If you look at the presentation slides here while you listen, it is almost like being there!

I've just sent another dev release off to CPAN, 0.13_03 to test the recent Build changes that were necessary to get AMD64 boxen to correctly compile. It turns out that they really need the "-fPIC" flag at compilation and link time or else stuff blows up:

This link with go active sometime tomorrow: 

New stuff since 0.13_02:

Changes since 0.12:

   - Chebyshev Series Approximation, with tests and docs
   - Improved Deriv, Integration, Chebyshev, Combination and Roots docs
   - Improved introduction examples in Math::GSL
   - Improved Minimization subsystem tests, but it is not functional
   - Added example/deriv/basic

       This shows the simple fact that d/dx(sin(x)) = cos(x)

   - Added example/sf/erfc_check (thanks to Keith Lofstrom)

       Script which tests the erfc() special function against computing
       the integral definition with gsl_integration_qagiu()

   - Added example/vector/speed

       This shows a considerable performance boost using Math::GSL::Vectors
       instead of List::Util when searching for the min and max elements of
       large sets of random numbers.

   - Fixed return signature of gsl_deriv_* functions to return a flat list
   - Fix location of shared objects (Sisyphus)
   - Added raw() method to RNG objects
