# kthvalue¶

paddle. kthvalue ( x, k, axis=None, keepdim=False, name=None ) [source]

Find values and indices of the k-th smallest at the axis.

Parameters
• x (Tensor) – A N-D Tensor with type float32, float64, int32, int64.

• k (int) – The k for the k-th smallest number to look for along the axis.

• axis (int, optional) – Axis to compute indices along. The effective range is [-R, R), where R is x.ndim. when axis < 0, it works the same way as axis + R. The default is None. And if the axis is None, it will computed as -1 by default.

• keepdim (bool, optional) – Whether to keep the given axis in output. If it is True, the dimensions will be same as input x and with size one in the axis. Otherwise the output dimentions is one fewer than x since the axis is squeezed. Default is False.

• name (str, optional) – For details, please refer to Name. Generally, no setting is required. Default: None.

Returns

tuple(Tensor), return the values and indices. The value data type is the same as the input x. The indices data type is int64.
