Usage

FFT

<?php
use Webit\Math\Fft\FftCalculatorRadix2;
use Webit\Math\Fft\Dimension;
use Webit\Math\ComplexNumber\ComplexArray;

// FFT
$calculator = new FftCalculatorRadix2();
$signal = ComplexArray::create(array(123, 456, 789, 1111));

$fft = $calculator->calculateFft($signal, Dimension::create(4)); // ComplexArray

IFFT

<?php
use Webit\Math\Fft\IFftCalculator;
use Webit\Math\Fft\FftCalculatorRadix2;
use Webit\Math\Fft\Dimension;
use Webit\Math\ComplexNumber\ComplexArray;

// FFT
$calculator = new IFftCalculator(new FftCalculatorRadix2());
$signal = ComplexArray::create(array(123, 456, 789, 1111));

$ifft = $calculator->calculateIFft($signal, Dimension::create(4)); // ComplexArray
