ferray-fft

FFT operations for the ferray scientific computing library.

What's in this crate

• 1D: fft, ifft, rfft, irfft, hfft, ihfft
• 2D: fft2, ifft2, rfft2, irfft2
• ND: fftn, ifftn, rfftn, irfftn
• Frequencies: fftfreq, rfftfreq, fftshift, ifftshift
• Plan caching: thread-local FFT plan reuse for repeated transforms
• Normalization: Backward, Forward, Ortho modes matching NumPy
• Powered by rustfft with AVX2+FMA SIMD butterflies

Usage

use ferray_fft::{fft, fftfreq};
use ferray_core::prelude::*;

let signal = Array1::<f64>::linspace(0.0, 1.0, 1024)?;
let spectrum = fft(&signal, None, None, None)?;
let freqs = fftfreq(1024, 1.0 / 1024.0)?;

This crate is re-exported through the main ferray crate with the fft feature.
