mindspore.Tensor.atan2

Tensor.atan2(y)[source]

Returns arctangent of x/y element-wise.

x refers to self tensor.

It returns \(\theta\ \in\ [-\pi, \pi]\) such that \(x = r*\sin(\theta), y = r*\cos(\theta)\), where \(r = \sqrt{x^2 + y^2}\).

Args of x and y comply with the implicit type conversion rules to make the data types consistent. If they have different data types, the lower precision data type will be converted to the relatively highest precision data type.

Parameters

y (Tensor) – The input tensor. It has the same shape with x after broadcasting, or the shape of x is the same as y after broadcasting.

Returns

Tensor, the shape is the same as the one after broadcasting, and the data type is same as x.

Raises

  • TypeError – If x or y is not a Tensor.

  • RuntimeError – If the data type of x and y conversion of Parameter is required when data type conversion of Parameter is not supported.

Supported Platforms:

Ascend CPU GPU

Examples

>>> x = Tensor(np.array([0, 1]), mindspore.float32)
>>> y = Tensor(np.array([1, 1]), mindspore.float32)
>>> output = x.atan2(y)
>>> print(output)
