Calling Mathematica functions from ROOT

[Barbara Storaci]

Dear ROOT-Experts,

I discovered the possibility of calling Mathematica functions from ROOT at this
link <http://root.cern.ch/drupal/content/how-use-mathematica-root>.
This sounds exactly what I need. On the other hand the documentation in this
page looked obsolete. Is there any more recent documentation? Does this work
with the recent Mathematica versions (i.e. 9) or only with the old 5.1?

In my case what I would like to do is to write a new root/roofit class (in fact a new pdf
in root that derives from the usual RooAbsPdf) and call some mathematica function
in this class. Normally I'm compiling this new class with ".L RooAbsBNQ.cp++"
command inside the interpreter. How can I can integrate Mathematica calls in
this context?

Thanks a lot in advance,

Barbara

Hi again

just to add a bit of context to my request, it looks like the HOWTO guide refers to
some old version of ROOT and some extremely old version of Mathematica
(I browsed the several directories of the parc project on AFS and found the MathLink
module only within the 5.x versions).

Cheers,
Barbara

Dear Barbara,

Lorenzo will be back next week. I am sure he will be able to help you.
Cheers,

Dear Barbara,

Yes, it is true the iROOT instructions to use Mathematica code in ROOT refers to old Mathematica versions. I did not try them since a long time. I see that now new versions of Mathematica (I think from version 8), have a new way to call Mathematica functions from compiled C/C++ code. See

https://reference.wolfram.com/language/guide/CLanguageInterface.html

However, I think the MathLink module should be still available in the new versions. I don't have a time to see how to make it work with the new Mathematica version. If you find a way to solve this, please let me know and I will update the documentation.

But, just for curiosity, why do you want to use Mathematica ? Are you missing a mathematical function or an algorithm in ROOT that you need to use in RooFit ?

Best Regards

Lorenzo
