mindspore.numpy.arctan2

mindspore.numpy.arctan2(x1, x2, dtype=None)

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

说明

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

参数

• x1 (Tensor) – input tensor.

• x2 (Tensor) – input tensor.

• dtype (mindspore.dtype, optional) – Defaults to None. Overrides the dtype of the output Tensor.

返回

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
