PalmFFT

The Infinite Monkey Derivative of PocketFFT.

It's technically a dirty-room implementation, but my brain is clean. fuck.

I wanted to release this repository as Public Domain but released as BSD 3-clause cuz am afraid of lawyers kek

What it can do

• Complex FFT, Basic complex arithmetics. That's it.
• Real FFT? No, I have my life.
• Try searching unsafe, You won't find any
• Peak Dependency Minimalism™

How to use

cargo add palmfft --feature num-complex

use palmfft::{CfftPlan, Complex};

// just a random data
let n = 1024;
let mut data = vec![Complex::new(0.0, 0.0); n];
// ... fuck around with the data vector ...
let fct = 1.0 / data.len() as f64; // this is a scale factor

// initialise fft plan, no mismatch allowed
let plan = CfftPlan::new(data.len());

plan.forward(&mut data, 1.0); // fft
plan.backward(&mut data, fct); // ifft

Again, fuck.
