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
