Can someone show an example of a project where implementing this would make a measurable improvement?
Here is a variation of the same, with an FFT instead to give a more realistic comparison. ``` use std::time::Instant; use rustfft::{FftPlanner, num_complex::Complex}; const LEN: usize = 32*1024*1024; fn main()...
See https://github.com/ejmahler/RustFFT/issues/116
Well RustFFT relies on the standard library for a number of things. There are hashmaps, arcs, vecs etc. It would take a major redesign of the entire library to remove...
I would guess that the input vector is modified by fftw, so that you give different input to the two ffts.
@TheSirC Can this be closed?
I have a practical question. Would thos benefit from being part of RustFFT, or could it just as well be a separate crate? For real-to-complex transforms I have made a...
I needed the same thing and ended up making this: https://crates.io/crates/realfft It's a simple wrapper of RustFFT that does real to complex fft, and complex to real ifft. And yes...
I think these two are by far most common use cases: - Transform to get spectrum of real valued data. Needs real-to-complex fft. - Transform real valued data, modify the...
Oh, didn't see that one. Not sure which one is worst then, my #3 or the R2HC format...
