NAME
     norm -- normlalise amplitude of PRW text vectors.

SYNOPSIS
     norm (-s statfile) <pvin.txt >pvout.txt

DESCRIPTION
     norm is a program to process a text stream of pattern vector
     data  in  the  vector labelled format accepted by gendat. If
     the input pattern is R rows by C columns, the program calcu-
     lates  for vector the mean and variance of all the values in
     the vector.  It then applies a scaling to  ensure  that  the
     mean is zero and the variance 1.
     An option allows the input of a global mean and variance for
     the  vectors  (as output by vecstat ) which replaces vector-
     by-vector normalisation.

OPTIONS
     -I         Identify program name and version number.

     -s statfile
                File of global means and variances as  output  by
                vecstat.
