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

For usage examples, see files returned by:

Thanks for your answer, I have a Gaussian spectrums (Neutron mass spectrum) and I want to move all the points around the peak of spectrum to peak point (for different spectrum the spacing around the peak is different). TMinuit can help me?

I have no idea what you are trying to do.

Here’s a simple example how one can fit a gaussian peak (in a histogram) using several different methods and fit options:
