cupy.in1d¶

cupy.in1d(ar1, ar2, assume_unique=False, invert=False)[source]¶

Tests whether each element of a 1-D array is also present in a second array.

Returns a boolean array the same length as ar1 that is True where an element of ar1 is in ar2 and False otherwise.

Parameters:	ar1 (cupy.ndarray) – Input array. ar2 (cupy.ndarray) – The values against which to test each value of `ar1`. assume_unique (bool, optional) – Ignored invert (bool, optional) – If `True`, the values in the returned array are inverted (that is, `False` where an element of `ar1` is in `ar2` and `True` otherwise). Default is `False`.
Returns:	The values `ar1[in1d]` are in `ar2`.
Return type:	cupy.ndarray, bool
