MEAN(1G)                COMMAND REFERENCE                MEAN(1G)



NAME
     mean - arithmetic mean

SYNOPSIS
     mean [ -fn ] [ -pn ] [ -nn ] [ vector ... ]

DESCRIPTION
     Output is the mean of the elements in the input vector(s).
     The input may optionally be trimmed.  If no vector is given,
     the standard input is assumed.

OPTIONS
     -fn  Trim (1/n)*r elements from each end, where r is the
          rank of the input vector.

     -pn  Trim n*r elements from each end, where n is between 0
          and .5.

     -nn  Trim n elements from each end.

EXAMPLES
     The following example outputs the mean of the middle 50% of
     the elements of A, i.e., A is trimmed by 25% of its elements
     from both ends.

          mean -p.25 A
