FFit v2.2-S - Function fitting
===============================

Fit almost any analytical function through a set of data points,
calculate values of the fitted function, and plot a graph of the
data and the fitted function on screen or a dot matrix printer.
There are also secondary facilities for finding the minimum or
maximum value of a function, or for solving a function for any
specified values.

FFit is ideal for engineers and scientists who need to fit any type
of function through a set of data points which contain experimental
errors. Multiple non-linear regression is used, so you do not have to
worry about whether your function can be linearised. FFit is very
easy to use, and incorporates on-line help with over 130 screens of
information for those who want to delve deeper into its facilities.
The graphics utility lets you see your data and the fitted function
with as little as 2 keystrokes, and you can tailor the graph to your
own requirements.
