The patch adds the `minuit` command which is a clone of
the `fit` command that utilizes CERN Minuit library for
function fiting. The syntax of `minuit` command is
based on the one of the `fit` command with two main
- for the time being it supports only 2D fits
- for the time being it supports only 6 column input:
Quoting MINUIT documentation:
What MINUIT is intended to do
MINUIT is conceived as a tool to find the minimum value
of a multi-parameter function and analyze the shape of
the function around the minimum. The principal
application is foreseen for statistical analysis,
working on chisquare or log-likelihood functions, to
compute the best parameter values and uncertainties,
including correlations between the parameters. It is
especially suited to handle difficult problems,
including those which may require guidance in order to
find the correct solution.
What MINUIT is not intended to do
Although MINUIT will of course solve easy problems
faster than complicated ones, it is not intended for
the repeated solution of identically parametrized
problems (such as track fitting in a detector) where a
specialized program will in general be much more efficient.
As it is a initial release of the patch it lacks some
functionality and was not tested thoroughly yet.
CERN Minuit library is written in C++, the patch
includes a Wrapper that allows gnuplot to call Minuit
objects and methods from C.
