RustFFT

RustFFT is a mixed-radix FFT implementation written in Rust. See the documentation for more details.

If you're looking for the experimental AVX-accelerated release, check out the SIMD branch.

Usage

```rust // Perform a forward FFT of size 1234 use rustfft::{FFTplanner, num_complex::Complex};

let mut planner = FFTplanner::new(false); let fft = planner.plan_fft(1234);

let mut input: Vec> = vec![Complex{ re: 0.0, im: 0.0 }; 4096]; let mut output: Vec> = vec![Complex{ re: 0.0, im: 0.0 }; 4096];

fft.process(&mut input, &mut output); ```

Compatibility

The rustfft crate requires rustc 1.31 or greater.
