torch.angle

torch.angle(input, *, out=None) → Tensor

Computes the element-wise angle (in radians) of the given input tensor.

$$\text{out}_{i} = angle(\text{input}_{i})$$

Parameters:

input (Tensor) – the input tensor.

Keyword Arguments:

out (Tensor, optional) – the output tensor.

Note

Starting in PyTorch 1.8, angle returns pi for negative real numbers, zero for non-negative real numbers, and propagates NaNs. Previously the function would return zero for all real numbers and not propagate floating-point NaNs.

Example:

>>> torch.angle(torch.tensor([-1 + 1j, -2 + 2j, 3 - 3j]))*180/3.14159
tensor([ 135.,  135,  -45])
