**Math::FFT - 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 method...
