Hi monks. I am quite new to perl, except from some easy regex stuff :P so, today I was trying to setup a normalizing function, which would ideally work on arrays. The idea is that we have an input array whose items have to be normalized between 0 and 1. Normalization is quite simple, achieved by:  normalized_array_item = (array_item - array_min) / (array_max - array_min) So here is a draft of what I prepared.

 
sub normalizer {
    # to normalize an input array bw 0 and 1
    use List::Util qw( min max );    # import min and max module
    my $min_numarray = min @array; # get min of args
    my $max_numarray = max @array; # get max of args
    foreach my $element(@array) {    # loop over args
        my $numdiv = $element - $min_numarray;    # numerator: n - min
+ total
        my $numden = $max_numarray - $min_numarray; # denominator: max
+ total - min total 
        my $normalized = my $numdiv / $numden; # normalize
    }
    return $normalized;
}

Actually I would like my function to return the whole normalized array. Could you help me with that? Thanks
