NAME Algorithm::MedianSelect::XS - Median finding algorithm SYNOPSIS use Algorithm::MedianSelect::XS qw(median); my @numbers = (1,2,3,5,6,7,9,12,14,19,21); print median(@numbers); print median(\@numbers); print median(\@numbers, { algorithm => 'bubble' }); # slow algorithm print median(\@numbers, { algorithm => 'quick' }); # default algorithm DESCRIPTION Algorithm::MedianSelect::XS finds the item which is smaller than half of the integers and bigger than half of the integers. FUNCTIONS median Takes a list or reference to list of integers and returns the median number. Optionally, the algorithm being used for computation may be specified within a hash reference. See SYNOPSIS for algorithms currently available. EXPORT "median()" is exportable.
