mindspore.numpy.arctan2

mindspore.numpy.arctan2(x1, x2, dtype=None)[源代码]

Element-wise arc tangent of \(x1/x2\) choosing the quadrant correctly.

Note

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

Parameters

x1 (Tensor) – input tensor.
x2 (Tensor) – input tensor.
dtype (mindspore.dtype, optional) – Defaults to None. Overrides the dtype of the output Tensor.

Returns

Tensor or scalar, the sum of x1 and x2, element-wise. This is a scalar if both x1 and x2 are scalars.

Supported Platforms:: Ascend CPU GPU

Examples

>>> import mindspore.numpy as np
>>> x1 = np.array([-1, +1, +1, -1])
>>> x2 = np.array([-1, -1, +1, +1])
>>> output = np.arctan2(x1, x2)
>>> print(output)
