good morning monks, i´ve got a lil issue here, i was hoping you could help me with. i´ve got an array with numbers (40-300) now i want to make a FFT(Fast Fourier Transformation)with the array to then find the key points with the highest magnitude from certain ranges 40-80, 80-120, 120-180, 180-300. I dont come further than that: 
use strict;
use warnings;

use Math::FFT;

my $series[0] = 123;
my $series[1] = 260;
my $series[2] = 46;
my $series[3] = 94;
#   ...  etc  ... 

my $fft = new Math::FFT(@series);

Does any one know how to get on this, i cant figure it out. Thanks in advance! * Merle
