cupynumeric.argpartition#

cupynumeric.argpartition( a: ndarray, kth: int | Sequence[int], axis: int | None = -1, kind: SelectKind = 'introselect', order: str | list[str] | None = None, ) → ndarray#

Perform an indirect partition along the given axis.

Parameters:

a (array_like) – Input array.
kth (int or Sequence[int])
axis (int or None, optional) – Axis to partition. By default, the index -1 (the last axis) is used. If None, the flattened array is used.
kind ({'introselect'}, optional) – Currently not supported.
order (str or list[str], optional) – Currently not supported.

Returns:

out – Array of indices that partitions a along the specified axis. It has the same shape as a.shape or is flattened in case of axis is None.

Return type:

ndarray[int]

Notes

The current implementation falls back to cupynumeric.argsort.
