Function microfft::complex::cfft_4

pub fn cfft_4(input: &mut [Complex32]) -> &mut [Complex32]

Perform an in-place 4-point CFFT.

Example

use microfft::{Complex32, complex::cfft_4};

let mut input = [Complex32::default(); 4];
let result = cfft_4(&mut input);

Panics

Panics if input has a length other than 4.
