Calling ROOT::Math::wigner_6j(5,5,4,4,4,1)

Greetings all,

I am trying to use the ROOT special math function wigner_6j by calling “ROOT::Math::wigner_6j(5,5,4,4,4,1)” at the command line.

The error I get is as follows

[quote]Error: Function wigner_6j(5,5,4,4,4,1) is not defined in current scope (tmpfile):1:
*** Interpreter error recovered ***

If I call another function in the same library (e.g. ROOT::Math::tgamma(.5)) I get an appropriate answer.

Any suggestions for what I might be doing wrong

The version of ROOT I am using is a as follow (ROOT 5.29/03 (trunk@39055, Jun 02 2011, 09:09:23 on linuxx8664gcc). The version is about a month old but I rebuilt it to see if that was my problem.

To build ROOT I used the following configure string “./configure --with-clang --enable-roofit --enable-minuit2 --enable-gsl-shared” followed by make.


Greetings all,

I really need help with calling the wigner_6j function. It is listed as being part of the mathmore library and the numbers I am using as input to call it should generate a valid number output.

Any guidance at all would be greatly appreciated.

Hi Russel,

You might have better luck posting math question in the “Stat and Math Tools” Forum.


Thanks Philippe, I’ll give it a try.
