* Dependencies: com.example.ueberwachungssystem.Detection.Signalverarbeitung.Complex.java

*
|

* Compute the FFT and inverse FFT of a length n complex sequence

* using the radix 2 Cooley-Tukey algorithm.
|
|

* Bare bones implementation that runs in O(n log n) time and O(n)

* than performance.
|
|
||||||
*
|
|
||||||
* This implementation uses the primitive root of unity w = e^(-2 pi i / n).
|

* Limitations
|

* -----------
|
|
||||||
* - assumes n is a power of 2
|
|
||||||
*
|
|
||||||
* - not the most memory efficient algorithm (because it uses
|
|
||||||
* an object type for representing complex numbers and because
|
|
||||||
* it re-allocates memory for the subarray, instead of doing
|
|
||||||
* in-place or reusing a single temporary array)
