cupyx.scipy.signal.czt_points#

cupyx.scipy.signal.czt_points(m, w=None, a=1 + 0j)[source]#

Return the points at which the chirp z-transform is computed.

Parameters:

  • m (int) – The number of points desired.

  • w (complex, optional) – The ratio between points in each step. Defaults to equally spaced points around the entire unit circle.

  • a (complex, optional) – The starting point in the complex plane. Default is 1+0j.

Returns:

out – The points in the Z plane at which CZT samples the z-transform, when called with arguments m, w, and a, as complex numbers.

Return type:

ndarray
