`scipy._lib.array_api_extra._delegation:setdiff1d`

source: /scipy/_lib/array_api_extra/_delegation.py :634

Signature

   def     setdiff1d (    x1  :  Array | complex    ,    x2  :  Array | complex    ,  / ,     assume_unique  :  bool    =  False   ,    xp  :  ModuleType | None    =  None     )   →  Array

Summary

Find the set difference of two arrays.

Extended Summary

Return the unique values in x1 that are not in x2.

Parameters

x1 : array | int | float | complex | bool: Input array.
x2 : array: Input comparison array.
assume_unique : bool: If True, the input arrays are both assumed to be unique, which can speed up the calculation. Default is False.
xp : array_namespace, optional: The standard-compatible namespace for x1 and x2. Default: infer.

Returns

: array: 1D array of values in x1 that are not in x2. The result is sorted when assume_unique is False, but otherwise only sorted if the input is sorted.

Examples

import array_api_strict as xp
import array_api_extra as xpx

⚠

x1 = xp.asarray([1, 2, 3, 2, 4, 1])
x2 = xp.asarray([3, 4, 5, 6])
xpx.setdiff1d(x1, x2, xp=xp)
