mindspore.ops.Atan2

class mindspore.ops.Atan2[source]

Returns arctangent of x/y element-wise.

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

Inputs of x and y comply with the implicit type conversion rules to make the data types consistent. If they have different data types, lower priority data type will be converted to relatively highest priority data type. RuntimeError exception will be thrown when the data type conversion of Parameter is required.

Inputs:
  • x (Tensor) - The input tensor. \((N,*)\) where \(*\) means, any number of additional dimensions. The data type will give priority to the high-precision data type

  • y (Tensor) - The input tensor. It has the same shape with x. The data type will give priority to the high-precision data type.

Outputs:

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.

Supported Platforms:

Ascend CPU GPU

Examples

>>> x = Tensor(np.array([0, 1]), mindspore.float32)
>>> y = Tensor(np.array([1, 1]), mindspore.float32)
>>> atan2 = ops.Atan2()
>>> output = atan2(x, y)
>>> print(output)
