def _lloyd_iteration(sample: np.ndarray, decay: float, qhull_options: str) → np.ndarray

Lloyd-Max algorithm iteration.

sample : array_like (n, d): The sample to iterate on.
decay : float: Relaxation decay. A positive value would move the samples toward their centroid, and negative value would move them away. 1 would move the samples to their centroid.
qhull_options : str: Additional options to pass to Qhull. See Qhull manual for details. (Default: "Qbb Qc Qz Qj Qx" for ndim > 4 and "Qbb Qc Qz Qj" otherwise.)

sample : array_like (n, d): The sample after an iteration of Lloyd's algorithm.
