Hi Lorenzo,
The implementation of the integral is worked out a bit more and the results is quite good, and it runs very fast now, but still got a lot of warnings and NaN values.
I updated the the .cxx and .h file.RooMyPdf.cxx (5.7 KB) RooMyPdf.h (1.5 KB)
Could you try to run it please?
Best regards,
Diallo.
