mindspore.numpy.searchsorted

mindspore.numpy.searchsorted(a, v, side='left', sorter=None)[source]

Finds indices where elements should be inserted to maintain order. Finds the indices into a sorted array a such that, if the corresponding elements in v were inserted before the indices, the order of a would be preserved.

Parameters

  • a (Union[list, tuple, Tensor]) – 1-D input array. If sorter is None, then it must be sorted in ascending order, otherwise sorter must be an array of indices that sort it.

  • v (Union[int, float, bool, list, tuple, Tensor]) – Values to insert into a.

  • side ('left', 'right', optional) – If ‘left’, the index of the first suitable location found is given. If ‘right’, return the last such index. If there is no suitable index, return either 0 or N (where N is the length of a).

  • sorter (Union[int, float, bool, list, tuple, Tensor]) – 1-D optional array of integer indices that sort array a into ascending order. They are typically the result of argsort.

Returns

Tensor, array of insertion points with the same shape as v.

Raises

ValueError – if argument for side or sorter is invalid.

Examples

>>> from mindspore import numpy as np
>>> print(np.searchsorted([1,2,3,4,5], 3))
2
>>> print(np.searchsorted([1,2,3,4,5], 3, side='right'))
3
>>> print(np.searchsorted([1,2,3,4,5], [-10, 10, 2, 3]))
[0 5 1 2]
