* Compilation: javac FFT.java
|

* Execution: java FFT n
|
||||
* Dependencies: 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)
|
||||
* space. Our goal is to optimize the clarity of the code, rather
|
||||
* than performance.
|
||||
*
|
||||
* This implementation uses the primitive root of unity w = e^(-2 pi i / n).
|
||||
* Some resources use w = e^(2 pi i / n).
|
||||
*
|
||||
* Reference: https://www.cs.princeton.edu/~wayne/kleinberg-tardos/pdf/05DivideAndConquerII.pdf
|
||||
*
|
||||
* 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)
|
||||

* For an in-place radix 2 Cooley-Tukey FFT, see
