Function czt_points 

Source 
pub fn czt_points(
    m: usize,
    a: Option<Complex<f64>>,
    w: Option<Complex<f64>>,
) -> Array1<Complex<f64>>
Expand description

Compute points at which the chirp z-transform samples

Returns points on the z-plane where CZT evaluates the z-transform. The points follow a logarithmic spiral defined by a and w.

§Parameters

  • m: Number of output points
  • a: Starting point on the complex plane (default: 1+0j)
  • w: Ratio between consecutive points (default: exp(-2j*pi/m))

§Returns

Array of complex points where z-transform is evaluated
