Function fftfreq

Source 
pub fn fftfreq<F, I>(n: usize, d: F) -> I
where
    F: Float + FloatConst + NumAssign + 'static,
    usize: AsPrimitive<F>,
    for<'c> I: Iterable<OwnedItem = F, Item<'c> = &'c F>,
Expand description

Computes the frequency values associated fft based on n the length of the collection and d the sampling period
