The MINUIT package performs minimization and analysis of the shape of a multi-parameter function. It is intended to be used on Chisquare or likelihood functions for fitting data and finding parameter errors and correlations. The more important options offered are:

Variable metric (Fletcher) minimization

Monte Carlo minimization

Simplex (Nelder and Mead) minimization

Parabolic error analysis (error matrix)

MINOS (non-linear) error analysis

Contour plotting

Fixing and restoring parameters

Global minimization

Usage:

MINUIT can be used either

as a ``master'' batch program which reads and executes commands appearing in the input data stream;

or

as a ``master'' interactive program which reads and executes commands given from the terminal;

or

as a Fortran callable ``slave'' package, called from the user program or from an intermediate package such as PAW or HBOOK;

or

any combination of the above.
