_ROOT Version:5.34
Platform: Not Provided
Compiler: Not Provided

I’m using missing mass of neutron and I need to fit by TMinuit package. I don’t know how can I download and work with TMinuit .
Thanks in advance

The MINUIT and Minuit2 (optional) are provided by ROOT 5.34.

For usage examples, see files returned by:

grep -l -r -i minuit ${ROOTSYS}/t[eu]*
