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

```rust extern crate chfft; extern crate numcomplex; use numcomplex::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::::with_len(input.len()); let output = fft.forward(&input); println!("the transform of {:?} is {:?}", input, output); } ```
