chfft

Fastest Fourier Transform library implemented with pure Rust.

How-to Use

See the crate documentation for more details.

Features

• CFft1D - Perform a complex-to-complex one-dimensional Fourier transform.

• CFft2D - Perform a complex-to-complex two-dimensional Fourier transform.

• Dct1D - Perform a discrete cosine transform.

• RFft1D - Perform a real-to-complex one-dimensional Fourier transform.

• Mdct1D - Perform a Modified discrete cosine transform.

Examples

extern crate chfft;
extern crate num_complex;
use num_complex::Complex;
use chfft::CFft1D;

fn main() {
    let input = [Complex::new(2.0, 0.0), Complex::new(1.0, 1.0),
                 Complex::new(0.0, 3.0), Complex::new(2.0, 4.0)];
    let mut fft = CFft1D::<f64>::with_len(input.len());
    let output = fft.forward(&input);
    println!("the transform of {:?} is {:?}", input, output);
}
