pub fn tukey(m: usize, alpha: f64) -> FerrayResult<Array<f64, Ix1>>Expand description
Tukey (cosine-tapered) window with taper ratio alpha ∈ [0, 1].
alpha = 0 gives a rectangular window; alpha = 1 gives a Hann
window. The middle (1 - alpha) * (M - 1) samples are unity, and the
edges are tapered with a half-cosine.
