numpy.may_share_memory — NumPy v2.2 Manual (original) (raw)

Determine if two arrays might share memory

A return of True does not necessarily mean that the two arrays share any element. It just means that they might.

Only the memory bounds of a and b are checked by default.

Parameters:

a, bndarray

Input arrays

max_workint, optional

Effort to spend on solving the overlap problem. Seeshares_memory for details. Default for may_share_memoryis to do a bounds check.

Returns:

outbool

Examples

import numpy as np np.may_share_memory(np.array([1,2]), np.array([5,8,9])) False x = np.zeros([3, 4]) np.may_share_memory(x[:,0], x[:,1]) True
