How to get started with Minuit

Here it is shown how to run a MINUIT example of function minimization. The example is based on the Quadratic function in four parameters from chapter 7.7 from the Minimization tutorial and it is implemented in test/MnTutorial/Quad4FMain.cxx.

In the following it is described how one can run MINUIT in order to minimize this function, and verify that the result is correct. Both ways are described for SCRAM users at CERN (old, not anymore valid for Minuit2) and those who use autoconf/make (still valid).

• How to use Minuit for autoconf/make users
• OLD(valid only for Minuit SEAL version not for Minuit2): How to use Minuit for SCRAM users at CERN
• NEW: ROOT users have Minuit2 as part of the distribution. Binary ROOT distributions have normally Minuit2 as part of it. If ROOT has been installed from source, Minuit2 must be enabled at configure time by doing (when configuring ROOT):

  ./configure --enable-minuit2
  

A list of various Minuit examples is present here.
