mindspore.ops.angle

mindspore.ops.angle(input)

Returns the element-wise argument of a complex tensor. The elements in input are considered to be complex numbers of the form a+bj, where a is the real part and b is the imaginary part. The argument returned by this function is of the form $atan2(b,a)$.

Parameters

input (Tensor) – The input tensor. types: complex64, complex128.

Returns

Tensor, has the float32 or float64 type and the same shape as input.

Raises

• TypeError – If input is not a Tensor.

• TypeError – If the dtype of input is not one of: complex64, complex128.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore
>>> from mindspore import Tensor, ops
>>> input = Tensor([-1.5 + 7.8j, 3 + 5.75j], mindspore.complex64)
>>> output = ops.angle(input)
>>> print(output)
