Hi there!

During the last days I was looking for portable math modules for python.
There were some different uncoordinated attempts to wrap functions to
python. I wrapped successfully a lot of special functions to python2.0 .

Who does like to work on a complete interface to python?

I think it is possible to make different submodules with the work already
done. (eg. integration, matrices or special functions)

Please send your suggests!

Yours

It should be possible to use SWIG (www.swig.org) to do some wrapping
automatically -- have you looked at that?

 SWIG is a good way of producing wrappers quickly, but it isn't hard to 
produce a better OO interface for Python by hand. Also, I'm not sure that 
SWIG understands all of the Numpy structures (like ufuncs). 
 I'm interested in helping produce a Python wrapper for gsl, but I haven't 
paid attention to the Numpy developments for some time so it's likely that 
there are already people working on this(?) 

   Cheers,

I agree with Andrew Vick, my aim is to produce a simple exceptions raising
specfunc interface and for matrices a more elaborated access to
multidimensional arrays using the PySequence_* protocol.

Next week I will publish my wrap of gsl_sf_functions.

I am worried about portability of nan and posinf and neginf.
