Yes, that's the idea

Surely this should be log(exp(a)+exp(b))? That would be extremely useful, yes.

Hi All,
I'm thinking of adding some new ufuncs. Some possibilities are
- expadd(a,b) = exp(a) + exp(b) -- For numbers stored as logs:
- absdiff(a,b) = abs(a - b) -- Useful for forming norms
- absmax(a,b) = max(abs(a), abs(b))
- absadd(a,b) = abs(a) + abs(b) -- Useful for L_1 norm and

Hi Everyone,
I previously had a problem with installing numpy on a cluster of mine, but
it seemed to be resolved. The installation was successful and the numpy code
ran well. Unfortunately, this was not the case when I tried to run parallel
code. The other processors have difficulty finding a pa

one other suggestion:
if you want this to run any other machine, you might want to build gsl
as a static lib, so it will get linked directly into your extension, and

Thanks,
changing the library path and explicitly adding libraries =['gsl',

Thank you so much !

The issue with the LD_LIBRARY_PATH would come up in any case. You have
to put your gsl library folder before the system one if you want your
gsl library to be used.
For the cblas issue, it seems from Google you have to link against a
CBLAS library as well to use the GSL (for instance blas or atlas
And, additionally setting the environment variable LD_LIBRARY_PATH to
start with /data/home/u0038151/lib instead of ending with it, it picks
up my own gsl, and gives the error message

Hi Matthieu,
thank you for your prompt reply.

Dear all,
I am unsure about the correct place to put this question -- If this
isn't the correct list, please let me know which place is more
appropriate.
I am trying to build an extension module in python that calls a C
routine that depends on the GNU Scientific Library.
I am using swig to
