mindspore.numpy.copysign

mindspore.numpy.copysign(x1, x2, dtype=None)[源代码]

Changes the sign of x1 to that of x2, element-wise.

If x2 is a scalar, its sign will be copied to all elements of x1.

说明

Numpy arguments out, where, casting, order, subok, signature, and extobj are not supported. Complex inputs are not supported now.

参数

x1 (Union[int, float, list, tuple, Tensor]) – Values to change the sign of.
x2 (Union[int, float, list, tuple, Tensor]) – The sign of x2 is copied to x1. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).
dtype (mindspore.dtype, optional) – Defaults to None. Overrides the dtype of the output Tensor.

返回

Tensor or scalar. The values of x1 with the sign of x2. This is a scalar if both x1 and x2 are scalars.

异常

TypeError – If dtype of the input is not in the given types or the input can not be converted to tensor.

样例

>>> import mindspore.numpy as np
>>> output = np.copysign(np.array([1, -1, -1]), np.array([-1, 1, -1]))
>>> print(output)
[-1  1 -1]
