mlx.core.linalg.lu_factor# lu_factor(a: array, *, stream: None | Stream | Device = None) → Tuple[array, array]# Computes a compact representation of the LU factorization. 参数: a (array) -- Input array. stream (Stream, optional) -- Stream or device. Defaults to None in which case the default stream of the default device is used. 返回: The LU matrix and pivots array. 返回类型: tuple(array, array)
