Perl module to calculate Fast Fourier Transforms

This module implements some algorithms for calculating Fast Fourier Transforms for one-dimensional data sets of size 2^n. The data, assumed to arise from a constant sampling rate, is represented by an array reference '$data' (as described in the methods below), which is then used to create a 'Math::FFT' object as my $fft = Math::FFT->new($data); The methods available include the following.
